Using HTML Access
This guide, Using HTML Access, provides information about installing and using the HTML Access feature
of VMware Horizon™ with View™ to connect to virtual desktops without having to install any software on
a client system.
The information in this document includes system requirements and instructions for installing
HTML Access software on a View server and in a remote desktop virtual machine so that end users can use
a Web browser to access remote desktops.
IMPORTANT This information is written for administrators who already have some experience using View
and VMware vSphere. If you are a novice user of View, you might occasionally need to refer to the step-bystep instructions for basic procedures in the View Installation documentation and the View Administration
documentation.

IMPORTANT The remote desktop must be a virtual machine. Although you
can install View Agent on a physical machine, the Blast protocol used with
HTML Access cannot access a physical machine. View Agent must be
installed on a virtual machine.
Pool settings
HTML Access requires the following pool settings, in View Administrator:
n
The Max resolution of any one monitor setting must be 1920x1200 or
higher so that the remote desktop has at least 17.63MB of video RAM.
If you plan to use 3D applications or if end users will use a Macbook
with Retina Display or a Google Chromebook Pixel, see “Screen
Resolution,” on page 35.
n
The HTML Access setting must be enabled.
Configuration instructions are provided in “Prepare Remote Desktops and
Pools,” on page 12.
View Connection Server
View Connection Server with the HTML Access option must be installed on
the server.
n
8
HTML Access 2.6 requires View Connection Server 6.1 or View
Connection Server 6.0.x. If you have View Connection Server 6.0.x, you
must also run the separate HTML Access installer on the server.
VMware, Inc.
Chapter 1 Setup and Installation
n
HTML Access 2.5 requires View Connection Server 6.0.1. With this
version of View Connection Server, HTML Access 2.5 is built in.
n
HTML Access 2.4 requires View Connection Server 6.0. With this
version of View Connection Server, HTML Access 2.4 is built in.
By default, the HTML Access component is already selected in the View
Connection Server installer. Installation instructions are provided in the View
Installation document.
When you install the HTML Access component, the VMware Horizon View
Connection Server (Blast-In) rule is enabled in the Windows Firewall, so
that the firewall is automatically configured to allow inbound traffic to TCP
port 8443.
Security Server
View Security Server: The same version as View Connection Server must be
installed on the security server.
If client systems connect from outside the corporate firewall, VMware
recommends that you use a security server. With a security server, client
systems will not require a VPN connection.
NOTE A single security server can support up to 800 simultaneous
connections to Web clients.
Third-party firewalls
Display protocol for
View
VMware, Inc.
Add rules to allow the following traffic:
n
Servers (including security servers, View Connection Server instances,
and replica servers): inbound traffic to TCP port 8443.
n
Remote desktop virtual machines: inbound traffic (from servers) to TCP
port 22443.
Blast
When you use a Web browser to access a remote desktop, the Blast protocol
is used rather than PCoIP or Microsoft RDP. Blast uses HTTPS (HTTP over
SSL/TLS).

Using HTML Access
Preparing View Connection Server and Security Servers for
HTML Access
Administrators must perform specific tasks so that end users can connect to remote desktops using a Web
browser.
Before end users can connect to View Connection Server or a security server and access a remote desktop,
you must install View Connection Server with the HTML Access component and install security servers.
IMPORTANT For some versions of HTML Access, if you accidentally install View Connection Server without
the HTML Access option and then later decide that you do want the HTML Access component, you must
uninstall View Connection Server and then run the installer again with the HTML Access option selected.
When you uninstall View Connection Server, do not uninstall the View LDAP configuration, called the AD
LDS Instance VMwareVDMDS instance.
For other versions of HTML Access, you use a separate installer for HTML Access and so do not need to
reinstall View Connection Server.

Following is a check list of the tasks you must perform in order to use HTML Access:
1
Install View Connection Server with the HTML Access option on the server or servers that will
compose a View Connection Server replicated group.
By default, the HTML Access component is already selected in the installer. For installation
instructions, see the View Installation documentation.
NOTE To check whether the HTML Access component is installed, you can open the Uninstall a
Program applet in the Windows operating system and look for View HTML Access in the list.
2
If a separate HTML Access installer is required, on the View Connection Server host or hosts in a
replicated group, download the HTML Access installer from the View Downloads page, and run the
installer.
The installer is named VMware-Horizon-View-HTML-Access_X64-y.y.y-xxxxxx.exe, where y.y.y is the
version number, and xxxxxx is the build number.
3
If you use security servers, install View Security Server.
For installation instructions, see the View Installation documentation.
IMPORTANT The version of View Security Server must match the version of View Connection Server.
4
Verify that each View Connection Server instance or security server has a security certificate that can be
fully verified by using the host name that you enter in the browser.
For more information, see the View Installation documentation.
10
VMware, Inc.
Chapter 1 Setup and Installation
5
To use two-factor authentication, such as RSA SecurID or RADIUS authentication, verify that this
feature is enabled on View Connection Server.
For more information, see the topics about two-factor authentication in the View Administration
documentation.
6
If you use third-party firewalls, configure rules to allow inbound traffic to TCP port 8443 for all security
servers and View Connection Server hosts in a replicated group, and configure a rule to allow inbound
traffic (from View servers) to TCP port 22443 on remote desktops in the datacenter. For more
information, see “Firewall Rules for HTML Access,” on page 11.
After the servers are installed, if you look in View Administrator, you will see that the Blast Secure
Gateway setting is enabled on the applicable View Connection Server instances and security servers. Also,
the Blast External URL setting is automatically configured to use for the Blast Secure Gateway on the
applicable View Connection Server instances and security servers. By default, the URL includes the FQDN
of the secure tunnel external URL and the default port number, 8443. The URL must contain the FQDN and
port number that a client system can use to reach this View Connection Server host or security server host.
For more information, see "Set the External URLs for a View Connection Server Instance," in the View
Installation documentation.
NOTE You can use HTML Access in conjunction with VMware Workspace Portal to allow users to connect
to their desktops from an HTML5 browser. For information about installing Workspace Portal and
configuring it for use with View Connection Server, see the Workspace Portal documentation. For
information about pairing View Connection Server with a SAML Authentication server, see the View
Administration documentation.
Firewall Rules for HTML Access
To allow client Web browsers to use HTML Access to make connections to security servers, View
Connection Server instances, and remote desktops, your firewalls must allow inbound traffic on certain TCP
ports.
HTML Access connections must use HTTPS. HTTP connections are not allowed.
By default, when you install a View Connection Server instance or security server, the VMware Horizon
View Connection Server (Blast-In) rule is enabled in the Windows Firewall, so that the firewall is
automatically configured to allow inbound traffic to TCP port 8443.

Notes
Prepare Remote Desktops and Pools
Before end users can access a remote desktop, administrators must configure certain pool settings and install
View Agent on remote desktop virtual machines in the data center.
The HTML Access client is a good alternative when Horizon Client software is not installed on the client
system.
NOTE The Horizon Client software offers more features and better performance than the HTML Access
client. For example, with the HTML Access client, some key combinations do not work in the remote
desktop, but these key combinations do work with Horizon Client.
Prerequisites
n
Verify that your vSphere infrastructure and View components meet the system requirements for
HTML Access.
See “System Requirements for HTML Access,” on page 7.
n
Verify that the HTML Access component is installed with View Connection Server on the host or hosts
and that the Windows firewalls on View Connection Server instances and any security servers allow
inbound traffic on TCP port 8443.
See “Preparing View Connection Server and Security Servers for HTML Access,” on page 10.
n
If you use third-party firewalls, configure a rule to allow inbound traffic from View servers to TCP port
22443 on View desktops in the datacenter.
n
Verify that the virtual machine you plan to use as a desktop source has the following software installed:
a supported operating system and VMware Tools.
For a list of the supported operating systems, see “System Requirements for HTML Access,” on page 7.
n
Familiarize yourself with the procedures for creating desktop pools and entitling users to desktops. See
the topics about creating desktop pools in Setting Up Desktops and Applications in View.
n
To verify that the remote desktop is accessible to end users, verify that you have Horizon Client
software installed on a client system. You will test the connection by using the Horizon Client software
before attempting to connect from a browser.
For Horizon Client installation instructions, see the Horizon Client documentation site at
https://www.vmware.com/support/viewclients/doc/viewclients_pubs.html.
n
12
Verify that you have one of the supported browsers for accessing a remote desktop. See “System
Requirements for HTML Access,” on page 7.
VMware, Inc.
Chapter 1 Setup and Installation
Procedure
1
On the parent virtual machine you plan to use as a source for a linked-clone pool, or on the virtual
machine template that you plan to use for a full-clone pool, install View Agent.
The View Agent software includes an HTML Access component.
2
If you are creating a linked-clone pool, use vSphere Client to take a snapshot of the parent virtual
machine.
3
Use View Administrator to create a pool from this virtual machine, and enable the HTML Access
setting when completing the Add Desktop Pool wizard.
HTML Access is supported for virtual machine desktop pools and, if you have HTML Access 2.6,
session-based desktop pools on RDS hosts. Remote, hosted applications on RDS hosts are not
supported.
4
In the pool settings, verify that the Max resolution of any one monitor setting is 1920x1200 or higher.
5
Entitle users to this pool.
6
Use Horizon Client to log in to a desktop from this pool.
With this step, before you attempt to use HTML Access, you verify that the pool is working correctly.
7
Open a supported browser and enter a URL that points to your View Connection Server instance.
For example:
https://horizon.mycompany.com
Be sure to use https in the URL.
8
On the Web page that appears, click VMware Horizon HTML Access and log in as you would with the
Horizon Client software.
9
On the desktop selection page that appears, click a desktop icon.
You can now access a remote desktop from a Web browser when you are using a client device that does not
or cannot have Horizon Client software installed in its operating system.
What to do next
For added security, if your security policies require that the Blast agent on the remote desktop uses an SSL
certificate from a certificate authority, see “Configure HTML Access Agents to Use New SSL Certificates,”
on page 13.
Configure HTML Access Agents to Use New SSL Certificates
To comply with industry or security regulations, you can replace the default SSL certificates that are
generated by the HTML Access Agent with certificates that are signed by a Certificate Authority (CA).
When you install the HTML Access Agent on View desktops, the HTML Access Agent service creates
default, self-signed certificates. The service presents the default certificates to browsers that use
HTML Access to connect to View.
NOTE In the guest operating system on the desktop virtual machine, this service is called the VMware Blast
service.
To replace the default certificates with signed certificates that you obtain from a CA, you must import a
certificate into the Windows local computer certificate store on each View desktop. You must also set a
registry value on each desktop that allows the HTML Access Agent to use the new certificate.
VMware, Inc.
13
Using HTML Access
If you replace the default HTML Access Agent certificates with CA-signed certificates, VMware
recommends that you configure a unique certificate on each desktop. Do not configure a CA-signed
certificate on a parent virtual machine or template that you use to create a desktop pool. That approach
would result in hundreds or thousands of desktops with identical certificates.
Procedure
1
Add the Certificate Snap-In to MMC on a Horizon View Desktop on page 14
Before you can add certificates to the Windows local computer certificate store, you must add the
Certificate snap-in to the Microsoft Management Console (MMC) on the View desktops where the
HTML Access Agent is installed.
2
Import a Certificate for the HTML Access Agent into the Windows Certificate Store on page 15
To replace a default HTML Access Agent certificate with a CA-signed certificate, you must import the
CA-signed certificate into the Windows local computer certificate store. Perform this procedure on
each desktop where the HTML Access Agent is installed.
3
Import Root and Intermediate Certificates for the HTML Access Agent on page 16
If the root certificate and intermediate certificates in the certificate chain are not imported with the SSL
certificate that you imported for the HTML Access Agent, you must import these certificates into the
Windows local computer certificate store.
4
Set the Certificate Thumbprint in the Windows Registry on page 16
To allow the HTML Access Agent to use a CA-signed certificate that was imported into the Windows
certificate store, you must configure the certificate thumbprint in a Windows registry key. You must
take this step on each desktop on which you replace the default certificate with a CA-signed certificate.
Add the Certificate Snap-In to MMC on a Horizon View Desktop
Before you can add certificates to the Windows local computer certificate store, you must add the Certificate
snap-in to the Microsoft Management Console (MMC) on the View desktops where the HTML Access Agent
is installed.
Prerequisites
Verify that the MMC and Certificate snap-in are available on the Windows guest operating system where
the HTML Access Agent is installed.
Procedure

For example: 31 2a 32 50 1a 0b 34 b1 65 46 13 a8 0a 5e f7 43 6e a9 2c 3e
NOTE When you copy the thumbprint, do not to include the leading space. If you inadvertently paste
the leading space with the thumbprint into the registry key (in Step 7), the certificate might not be
configured successfully. This problem can occur even though the leading space is not displayed in the
registry value text box.
5
Start the Windows Registry Editor on the desktop where the HTML Access Agent is installed.
6
Navigate to the HKEY_LOCAL_MACHINE\SOFTWARE\VMware, Inc.\VMware Blast\Config registry key.
7
Modify the SslHash value and paste the certificate thumbprint into the text box.
8
Restart the VMware Blast service to make your changes take effect.
In the Windows guest operating system, the service for the HTML Access Agent is called VMware
Blast.
When a user connects to a desktop through HTML Access, the HTML Access Agent presents the CA-signed
certificate to the user's browser.
Upgrading the HTML Access Software
Install the latest version of HTML Access to obtain the latest updates and improvements.
To upgrade to the latest version of HTML Access, you must verify that the latest version of View
Connection Server is installed on all the instances in a replicated group.
For some releases of HTML Access, a separate HTML Access installer is required because no corresponding
maintenance release of View Connection Server is released. The following table shows which versions of
HTML Access require a separate installer.
Table 1‑3. Installer Requirements for HTML Access Versions
HTML Access Version

No separate installer
2.4
6.0
No separate installer
To complete the upgrade of HTML Access, you also must run the View Agent installer on the applicable
parent virtual machines or virtual machine templates for your desktop pools. The version of View Agent
should correspond to the version of View Connection Server.
IMPORTANT The View Agent installer now includes the HTML Access agent component that had been
included in the Remote Experience Agent for releases prior to Horizon 6.0 (with View). The Remote
Experience Agent was part of the Horizon View Feature Pack. To upgrade features that were installed with
the Remote Experience Agent, you can simply run the View Agent installer. This installer removes the
Remote Experience Agent before performing the upgrade. If, for some reason, you decide to manually
remove the Remote Experience Agent, be sure to do so before you run the installer for the new version of
View Agent.
VMware, Inc.

Using HTML Access
Uninstall HTML Access from View Connection Server
You can remove HTML Access by using the same method you use to remove other Windows software.
Procedure
1
On the View Connection Server hosts where HTML Access is installed, open the Uninstall a Program
applet provided by the Windows Control Panel.
2
Select VMware Horizon View HTML Access and click Uninstall.
3
(Optional) In the Windows Firewall for that host, verify that TCP port 8443 no longer allows inbound
traffic.
What to do next
Disallow inbound traffic to TCP port 8443 on the Windows Firewall of any paired security servers. If
applicable, on third-party firewalls, change the rules to disallow inbound traffic to TCP port 8443 for all
paired security servers and this View Connection Server host.
Data Collected by VMware
If your company participates in the customer experience improvement program, VMware collects data from
certain client fields. Fields containing sensitive information are made anonymous.
VMware collects data on the clients to prioritize hardware and software compatibility. If a View
administrator has opted to participate in the customer experience improvement program, VMware collects
anonymous data about your deployment to improve VMware's response to customer requirements. No data
that identifies your organization is collected. Client information is sent first to View Connection Server and
then on to VMware, along with data from servers, desktop pools, and remote desktops.
To participate in the VMware customer experience improvement program, the administrator who installs
View Connection Server can opt in while running the View Connection Server installation wizard, or an
administrator can set an option in View Administrator after the installation.

Configure the VMware Horizon Web Portal Page for End Users
You can configure this Web page to show or hide the icon for downloading Horizon Client or the icon for
connecting to a remote desktop through HTML Access. You can also configure other links on this page.
By default, the portal page shows both an icon for downloading and installing the native Horizon Client and
an icon for connecting through HTML Access. In some cases, however, you might want to have the links
point to an internal Web server, or you might want to make specific client versions available on your own
server. You can reconfigure the page to point to a different URL.
You can make installer links for specific client operating systems. For example, if you browse to the portal
page from a Mac OS X system, the link for the native Mac OS X installer appears. For Windows clients, you
can make separate links for 32-bit and 64-bit installers.
IMPORTANT If you upgraded from View Connection Server 5.x or an earlier release and did not have the
HTML Access component installed, and if you previously edited the portal page to point to your own server
for downloading Horizon Client, those customizations might be hidden after you install View Connection
Server 6.0 or later. With Horizon 6 or later, the HTML Access component is automatically installed during
an upgrade of View Connection Server.
If you already installed the HTML Access component separately for View 5.x, any customizations you made
to the Web page are preserved. If you did not have the HTML Access component installed, any
customizations you had made are hidden. The customizations for earlier releases reside in the portallinks.properties file, which is no longer used.
VMware, Inc.
21
Using HTML Access
Procedure
1
On the View Connection Server host, open the portal-links-html-access.properties file with a text
editor.
The location of this file is CommonAppDataFolder\VMware\VDM\portal\portal-links-htmlaccess.properties. For Windows Server 2008 operating systems, the CommonAppDataFolder directory is
C:\ProgramData. To display the C:\ProgramData folder in Windows Explorer, you must use the Folder
Options dialog box to show hidden folders.
NOTE Customizations for View 5.x and earlier releases resided in the portal-links.properties file,
which is located in the same CommonAppDataFolder\VMware\VDM\portal\ directory as the portal-linkshtml-access.properties file.
2
Edit the configuration properties to set them appropriately.
By default, both the installer icon and the HTML Access icon are enabled and a link points to the client
download page on the VMware Web site. To disable an icon, which removes the icon from the Web
page, set the property to false.
22
Option
Property Setting
Disable HTML Access
enable.webclient=false
If this option is set to false but the enable.download option is set to true,
the user is taken to a Web page for downloading the native Horizon Client
installer. If both options are set to false, the user sees the following
message: "Contact your local administrator for instructions
on accessing this Connection Server."
Disable downloading Horizon Client
enable.download=false
If this option is set to false but the enable.webclient option is set to true,
the user is taken to the HTML Access login Web page. If both options are
set to false, the user sees the following message: "Contact your local
administrator for instructions on accessing this Connection
Server."
Change the URL of the Web page
for downloading Horizon Client
link.download=https://url-of-web-server
Use this property if you plan to create your own Web page.

link.help
By default, this link points to a help system hosted on the VMware Web
site. The Help link appears in the upper-right corner of the screen. For the
HTML Access login screen and the desktop selector screen, the Help link is
a question mark icon.
(Optional) Change the URL for the Help link in the Horizon Client toolbar.
After you are logged in to a desktop, the Help link is a Help command in the drop-down menu on the
right end of the client. To change the URL for this link, edit the HELP_URL_VIEW property in the
appropriate file in the appropriate folder.
Option
Description
For HTML Access 2.6
On the View Connection Server host, the file is located in:
ViewConnectionServerInstallDir\webapps\portal\desktop\locale\
For HTML Access 2.4 and 2.5
On the remote desktop operating system (where View Agent is installed),
the file is located in:
C:\Program Files\VMware\VMware Blast\web\locale\
For example, if you are using English, edit the HELP_URL_VIEW property in the en.json file.
4
To have users download installers from a location other than the VMware Web site, place the installer
files on the HTTP server where the installer files will reside.
This location must correspond to the URLs you specified in the portal-links-html-access.properties
file from the previous step. For example, to place the files in a downloads folder on the View Connection
Server host, use the following path:
C:\Program Files\VMware\VMware View\Server\broker\webapps\downloads
The links to the installer files could then use relative URLs with the format /downloads/clientinstaller-file-name.

VMware, Inc.
Restart the View Web Component service.
23
Using HTML Access
Enable Desktops from RDS Hosts
With HTML Access 2.6, administrators can configure View Connection Server to allow a Microsoft RDS
(Remote Desktop Sessions) host to provide remote session-based desktops.
Prerequisites
See the Microsoft TechNet Web site for information on how to use the ADSI Edit utility on your Windows
operating system version. If you use a Windows Server 2012 RDS host, you might need to install the AD DS
& LDS Tools from the Remote Server Administration Tools (RSAT) in Add Roles & Features.
Procedure
1
Start the ADSI Edit utility on your View Connection Server host.
2
In the Connection Settings dialog box, select or connect to DC=vdi,DC=vmware,DC=int.
3
In the Computer pane, select or type localhost:389 or the fully qualified domain name (FQDN) of the
View Connection Server host followed by port 389.
For example: localhost:389 or mycomputer.mydomain.com:389
4
If the pool has already been created, find the name of the pool under the object OU=Applications, and
add BLAST in the pae-ServerProtocolLevel attribute.
5
Find the name of the farm under the object OU=Server Groups, and add BLAST in the paeServerProtocolLevel attribute.
The farm items now appear in the HTML Access Web client.
Using URIs to Configure HTML Access Web Clients
Using uniform resource identifiers (URIs), you can create a Web page or an email with links that end users
click to launch the HTML Access Web client, connect to View Connection Server, and launch a specific
desktop with specific configuration options.
You can simplify the process of connecting to a remote desktop by creating Web or email links for end users.
You create these links by constructing URIs that provide some or all of the following information, so that
your end users do not need to supply it:
24
n
View Connection Server address
n
Port number for View Connection Server
n
Active Directory user name
n
RADIUS or RSA SecurID user name, if different from Active Directory user name
n
Domain name
n
Desktop display name
n
Actions including browse, reset, log off, and start session
VMware, Inc.
Chapter 2 Configuring HTML Access for End Users
Syntax for Creating URIs for HTML Access
Syntax includes a path part to specify the server, and, optionally, a query to specify the user, desktop, and
desktop actions or configuration options.
URI Specification
Use the following syntax to create URIs for launching HTML Access Web clients:
https://[authority-part][?query-part]
IMPORTANT When coding the HTML hyperlinks or buttons that contain the URI, do not use target='_Blank'
in the link. This code is used to open a new browser window, but causes problems in Internet Explorer 9, 10,
and 11 browsers. If you use this code in an href, then if the user selects the Disconnect menu item, after the
desktop is disconnected, the client immediately attempts to reconnect. Also the user name and domain
name are not set.
authority-part
Specifies the server address and, optionally, a non-default port number.
Server names must conform to DNS syntax.
To specify a port number, use the following syntax:
server-address:port-number
query-part
Specifies the configuration options to use or the desktop actions to perform.
Queries are not case-sensitive. To use multiple queries, use an ampersand
(&) between the queries. If queries conflict with each other, the last query in
the list is used. Use the following syntax:
query1=value1[&query2=value2...]
Observe the following guidelines when creating the query-part:
n
If you do not use at least one of the supported queries, the default
VMware Horizon Web portal page is displayed.
n
In the query part, some special characters are not supported, and you
must use the URL encoding format for them, as follows: For the pound
symbol (#) use %23, for the percent sign (%) use %25, for the ampersand
(&) use %26, for the at sign (@) use %40, and for the backslash (\) use %5C.
For more information about URL encoding, go to
http://www.w3schools.com/tags/ref_urlencode.asp.
n
In the query part, non-ASCII characters must first be encoded according
to UTF-8 [STD63], and then each octet of the corresponding UTF-8
sequence must be percent-encoded to be represented as URI characters.
For information about encoding for ASCII characters, see the URL
encoding reference at http://www.utf8-chartable.de/.
VMware, Inc.
25
Using HTML Access
Supported Queries
This topic lists the queries that are supported for the HTML Access Web client. If you are creating URIs for
multiple types of clients, such as desktop clients and mobile clients, see the Using VMware Horizon Client
guide for each type of client system.
domainName
The domain associated with the user who is connecting to the remote
desktop.
userName
The Active Directory user who is connecting to the remote desktop.
tokenUserName
The RSA or RADIUS user name. Use this query only if the RSA or RADIUS
user name is different from the Active Directory user name. If you do not
specify this query and RSA or RADIUS authentication is required, the
Windows user name is used.
desktopId
The desktop display name. This name is the one specified in View
Administrator when the desktop pool was created. If the display name has a
space in it, the browser will automatically use %20 to represent the space.
action
Table 2‑1. Values That Can Be Used with the action Query
Value
Description
browse
Displays a list of available desktops hosted on the specified server.
You are not required to specify a desktop when using this action.
start-session
Launches the specified desktop. If no action query is provided and
the desktop name is provided, start-session is the default
action.
reset
Shuts down and restarts the specified desktop. Unsaved data is
lost. Resetting a remote desktop is the equivalent of pressing the
Reset button on a physical PC.
logoff
Logs the user out of the guest operating system in the remote
desktop.
Examples of URIs
You can create hypertext links or buttons with a URI and include these links in email or on a Web page.
Your end users can click these links to, for example, launch a particular remote desktop with the startup
options you specify.
URI Syntax Examples
Each URI example is followed by a description of what the end user sees after clicking the URI link. Note
that queries are not case-sensitive. For example, you can use domainName or domainname.
1
https://view.mycompany.com?domainName=finance&userName=fred
The HTML Access Web client is launched and connects to the view.mycompany.com server. In the login
box, the User name text box is populated with the name fred, and the Domain text box is populated
with finance. The user must supply only a password.
2
https://view.mycompany.com?desktopId=Primary%20Desktop&action=start-session
The HTML Access Web client is launched and connects to the view.mycompany.com server. The login box
prompts the user for a user name, domain name, and password. After a successful login, the client
connects to the desktop whose display name is displayed as Primary Desktop, and the user is logged in
to the guest operating system.
26
VMware, Inc.
Chapter 2 Configuring HTML Access for End Users
3
https://view.mycompany.com:7555?desktopId=Primary%20Desktop
This URI has the same effect as the previous example, except that it uses the nondefault port of 7555 for
View Connection Server. (The default port is 443.) Because a desktop identifier is provided, the desktop
is launched even though the start-session action is not included in the URI.
4
https://view.mycompany.com?desktopId=Primary%20Desktop&action=reset
The HTML Access Web client is launched and connects to the view.mycompany.com server. The login box
prompts the user for a user name, domain name, and password. After a successful login, the client
displays a dialog box that prompts the user to confirm the reset operation for Primary Desktop.
NOTE This action is available only if the View administrator has allowed end users to reset their
machines.
HTML Code Examples
You can use URIs to make hypertext links and buttons to include in emails or on Web pages. The following
examples show how to use the URI from the first URI example to code a hypertext link that says, Test Link,
and a button that says, TestButton.
<html>
<body>
<a href="https://view.mycompany.com?domainName=finance&userName=fred">Test Link</a><br>
<form><input type="button" value="TestButton" onClick="window.location.href=
'https://view.mycompany.com?domainName=finance&userName=fred'"></form> <br>
</body>
</html>
NOTE Do not use target='_Blank' in the link, as, for example, in the following code:
<a href="https://view.mycompany.com?desktopId=Primary%20Desktop&action=start-session"
target="_Blank">Test Link</a>
target='_Blank' is used to open a new browser window, but causes problems in Internet Explorer 9,10, and
11 browsers. If you use this code in an href, then if the user selects the Disconnect menu item, after the
desktop is disconnected, the client immediately attempts to reconnect. Also the user name and domain
name are not set.
Configure HTML Access Group Policy Settings
You can configure group policy settings that control the behavior of HTML Access on your remote desktops.
To apply these settings, add the HTML Access ADM template file to group policy objects (GPOs) in Active
Directory.
Prerequisites
n

Chapter 2 Configuring HTML Access for End Users
HTML Access Group Policy Settings
The HTML Access ADM Template file, Blast-enUS.adm, contains group policy settings that you can apply to
your remote desktops. After the template file is imported into Active Directory, the HTML Access group
policy settings are contained in the VMware Blast folder in the Group Policy Editor.
Table 2‑2. HTML Access Group Policy Settings
Setting
Description
Screen Blanking
Controls whether the remote virtual machine can be seen from outside of View during
an HTML Access session. For example, an administrator might use vSphere Web Client
to open a console on the virtual machine while a user is connected to the desktop
through HTML Access.
When this setting is enabled or not configured, and someone attempts to access the
remote virtual machine from outside of View while an HTML Access session is active,
the remote virtual machine displays a blank screen.
When this setting is disabled, under the preceding conditions, the remote virtual
machine displays the active View desktop session to the second remote accessor.
Session Garbage Collection
Controls the garbage collection of abandoned remoting sessions. When this setting is
enabled, you can configure the garbage collection interval and threshold.
The interval controls how often the garbage collector runs. You set the interval in
milliseconds.
The threshold determines how much time must pass after a session is abandoned
before it becomes a candidate for deletion. You set the threshold in seconds.
Audio playback
Controls whether audio playback is allowed on the remote desktop. By default, this
setting is enabled.
Image Quality
Controls the image quality of the remote display. There are three image quality
profiles, low, medium, and high. The encoder tries to use the best quality level possible,
given the constraints of available bandwidth, recent frame-rate, and the size of the
region that has recently changed in the current frame. The encoder keeps track of
which regions of the client screen are currently low- or medium-quality and
incrementally improves those areas to high quality.
When this setting is enabled, you can separately change the low-, medium-, and highquality JPEG settings to different values. The actual JPEG quality levels used at low,
medium, and high settings are individually configurable as numbers between 0 and
100.
Chroma subsampling is enabled according to the JPEG quality level chosen. Whenever
JPEG quality set to 80 or higher, chroma-subsampling is turned off and the ratio is set
to the highest available value, YUV-4:4:4. For JPEG quality set to 79 or below, the ratio
is set to YUV-4:2:0.
n Low JPEG Quality. By default, this value is 25. You can also set the low JPEG
chroma subsampling to various ratios. By default, the low ratio is set to the lowest
available value, 4:1:0.
n Mid JPEG Quality. By default, this value is 35. You can also set the low JPEG
chroma subsampling to various ratios. By default, the low ratio is set to the lowest
available value, 4:2:0.
n High JPEG Quality. By default, this value is 90.You can also set the high JPEG
chroma subsampling to various ratios. By default, the low ratio is set to the highest
available value, 4:4:4.

n Disabled in both directions
n Enabled in both directions
n Enabled server to client only (That is, allow copy and paste only from the remote
desktop to the client system.)
This setting applies to View Agent only.
For single-user remote desktops, when this setting is disabled or not configured, the
default value is Enabled client to server only. For session-based remote desktops on
RDS hosts (available with HTML Access 2.6), when this setting is disabled or not
configured, the default value is Disabled in both directions.
HTTP Service
Allows you to change the secured (HTTPS) TCP port for the Blast Agent service. The
default port is 22443.
Enable this setting to change the port number. If you change this setting, you must also
update settings on the firewall of the affected remote desktops (where View Agent is
installed).

Using HTML Access
Product Limitations
The Web client provided by HTML Access has product limitations with regard to sound playback and
keyboards.
n
Audio playback is not supported for Windows XP and Windows Vista remote desktops.
n
Internet Explorer 9 is not supported with HTML Access 2.6. For HTML Access 2.4 and 2.5, Internet
Explorer 9 is supported, but that version of the browser does not support many of the HTML5 features
provided with HTML Access. The features that are not supported by Internet Explorer 9 ( even with
HTML Access 2.4 or 2.5) include audio playback, clipboard redirection, mouse cursor changes, and fullscreen mode, among others.
n
If you use an Internet Explorer browser or a browser on handheld devices such as iPads and Android
tablets, the mouse pointer types do not change dynamically based on the location of the pointer.
Some of the unavailable types are the busy cursor, the drag cursor, and the resize cursor. For example,
on Internet Explorer browsers and mobile device browsers, when you move the mouse pointer over a
link on a Web page in a remote desktop, the mouse pointer does not change to a hand icon. If you move
the mouse pointer to the edge of a window, the pointer does not change to resizing arrows. If you are
editing text, the pointer does not change to a cursor. You can still perform the actions, but the pointer
remains a pointer.
n
Some modifier keys, special keys, and key combinations do not work in a remote desktop. For more
information, and for information about using international keyboards, see “Keyboard Limitations,” on
page 34 and “International Keyboards,” on page 35.
Keyboard Limitations
Regardless of the language used, some key combinations cannot be sent to the to a remote desktop.
Web browsers allow some key presses and key combinations to be sent to both the client and the destination
system. For other keys and key combinations, the input is processed only locally and is not sent to the
destination system. The key combinations that work on your system depend on the browser software, the
client operating system, and the language settings.
The following keys and keyboard combinations often do not work:
n
Ctrl+T
n
Ctrl+W
n
Ctrl+N
n
Windows key
n
Command key
n
Alt+Enter
n
Ctrl+Alt+any_key
n
Caps Lock+modifier_key (such as Alt or Shift)
n
Function keys, if you are using a Chromebook
IMPORTANT To input Ctrl+Alt+Del, use the Send Ctrl+Alt+Delete from the drop-down menu located at the
right end of the client menu bar.

Chapter 3 Using a Remote Desktop
International Keyboards
When using non-English keyboards and locales, you must use certain settings in your client system,
browser, and remote desktop. Some languages require you to use an IME (input method editor) on the
remote desktop.
With the correct local settings and input methods installed, you can input characters for the following
languages: English, Japanese, French, German, simplified Chinese, traditional Chinese, and Korean.

Screen Resolution
If the remote desktop has been configured with the correct amount of video RAM, the client can resize a
remote desktop to match the size of the client window. The default configuration is 36MB of video RAM,
which is comfortably more than minimum requirement of 16MB if you are not using 3D applications.
IMPORTANT To use the 3D rendering feature, you must allocate sufficient VRAM for each Windows 7 or
later remote desktop.
n
The software-accelerated graphics feature, available with vSphere 5.0 or later, allows you to use 3D
applications such as Windows Aero themes or Google Earth. This features requires 64MB to 128MB of
VRAM.
n
The shared hardware-accelerated graphics feature (vSGA), available with vSphere 5.1 or later, allows
you to use 3D applications for design, modeling, and multimedia. This feature requires 64MB to 512MB
of VRAM. The default is 96MB.
When 3D rendering is enabled, the maximum number of monitors is 1 and the maximum resolution is 1920
x 1200. Estimating the amount of vRAM you need for the Blast protocol is similar to estimating how much
vRAM is required for the PCoIP display protocol. For guidelines, see the section "RAM Sizing for Specific
Monitor Configurations When Using PCoIP" of the topic "Estimating Memory Requirements for Virtual
Desktops," in the View Architecture Planning document.
If you use a browser or Chrome device that has a high pixel density resolution, such as a Macbook with
Retina Display or a Google Chromebook Pixel, you can set the remote desktop to use that resolution. Select
the Toggle High Resolution Mode command from the drop-down menu located at the right end of the
client menu bar. To display this menu bar, click the down-arrow on the tab at the top-center of the window.

Using HTML Access
HTML Access also provides a Toggle Full Screen command from the drop-down menu.
IMPORTANT To use High Resolution mode in Full Screen mode, you must allocate sufficient VRAM for each
Windows 7 or later remote desktop. Estimating the amount of vRAM you need for the Blast protocol is
similar to estimating how much vRAM is required for the PCoIP display protocol. For guidelines, see the
section "RAM Sizing for Specific Monitor Configurations When Using PCoIP" of the topic "Estimating
Memory Requirements for Virtual Desktops," in the View Architecture Planning document.
Sound
If you use a Chrome device or a browser that supports WebSockets, you can play sound in your remote
desktop, but some limitations apply.
By default, sound playback is enabled for remote desktops, although your View administrator can set a
policy to disable sound playback.
Take into account the following guidelines:
n
Audio playback is not supported for Windows XP and Windows Vista remote desktops.
n
To turn up the volume, use the sound control on your client system, not the sound control in the remote
desktop.
n
Occasionally, the sound might go out of sync with the video.
n
In conditions of heavy network traffic, or if the browser is performing a lot of tasks (I/O), sound quality
might be reduced. Some browsers work better than others in this regard.
Copying and Pasting Text
Your View administrator can set this feature so that copy and paste operations are allowed only from your
client system to a remote desktop, or only from a remote desktop to your client system, or both, or neither.
Some restrictions apply.
This feature is available if you use a Chrome device or a browser that supports WebSockets.
Administrators configure the ability to copy and paste by using group policy objects (GPOs) that pertain to
View Agent in remote desktops. For more information, see “HTML Access Group Policy Settings,” on
page 29.
You can copy plain text or formatted text, including any non-ASCII characters, from Horizon Client to a
remote desktop, or the reverse, but the pasted text is plain text. You can copy and paste up to 5,000
characters.
You cannot copy and paste graphics. You also cannot copy and paste files between a remote desktop and
the file system on your client computer.
Use the Copy and Paste Feature
To copy and paste text, you must use the Paste Text and Get Copied Text commands from the drop-down
menu located at the right end of the client menu bar.
Prerequisites
36
n
The View administrator must either leave the default policy in effect, which allows users to copy from
client systems and paste into their remote virtual desktop, or else the administrator must configure
another policy that allows copying and pasting. For more information, see “HTML Access Group Policy
Settings,” on page 29.
n
You must use a Chrome device or a browser that supports WebSockets. Browsers that do not support
this technology do not display the Paste Text and Get Copied Text menu commands.
