Enhancements in Sun Java System Web Proxy Server Releases
The recent releases of Proxy Server includes the following enhancements.:
Performance Tuning, Sizing, and Scaling guide
A performance tuning, sizing, and scaling guide has been introduced in 4.0.11. This document
provides tuning, sizing, and scaling tips and suggestions; possible solutions to common
performance problems; and data from scalability studies. It also addresses miscellaneous
configuration and platform-specific issues. For more information, see Sun Java System Web
Proxy Server 4.0.11 Performance Tuning, Sizing, and Scaling Guide

Enhancements in Sun Java System Web Proxy Server Releases
Transparent Proxy
Proxy Server 4.0 supports transparent proxy for HTTP/1.1 connections. Transparent proxying
involves intercepting and processing web requests by using the proxy server, without the
knowledge or control of clients. For example, a router for a local network is configured to
redirect incoming TCP connections to the local port, in which the proxy server is active.
Add the following directive to the proxy server default object in the obj.conf file:
NameTrans fn="host-map"
This configuration enables the proxy server to use the HTTP Host: header of incoming
requests to identify and redirect the request to the target remote server.
Note – Transparent proxy servers that decide connections based on the HTTP Host: headers are
vulnerable to fake HTTP Host: headers forged through the active content. Therefore, suitable
ACL configurations must be implemented to prevent connection to web sites that might host
malicious content.
URL Mapping
URL Mapping has been implemented in Proxy Server 4.0.8. It enables the Proxy Server to act as
a reverse proxy. This feature enables Proxy Server to provide a single front-end hostname for
back-end application servers. Based on a requester's URI, access is provided to back-end
servers.
For more information about URL Mapping, see “Reverse Proxy Scenario” in Sun Java System
Web Proxy Server 4.0.11 Configuration File Reference.
For information about Server Application Functions (SAFs) used in URL Mapping, see “Server
Application Functions (SAFs)” in Sun Java System Web Proxy Server 4.0.11 Configuration File
Reference.
Registration with Sun Connection
You can use the Admin Server to register the Web Proxy Server with Sun Connection. Click the
Register with Sun Connection button, a client.jnlp application opens up. Follow the wizard
to complete the registration.

■
Support and training offerings
This feature is supported only on Solaris SPARC, x86 and Linux platforms. To avail this feature
on Solaris, you need to install SUNWservicetagr and SUNWservicetagu packages in SPARC and
x86 systems.
To avail this feature on Linux, you should install the sun-servicetag-1.0.0-1.0.i386.rpm.
Monitoring Server
The monitoring capabilities of Sun Java System Web Proxy Server provides a detailed list of the
server parameters that you can monitor at instance level.
From the Web Proxy Administration Server, you can perform the following actions:
■
■
View server statistics at an instance level.
Enable/Disable at an instance level.
▼ Monitoring Server
1
Access the Administration Server
2
Click the Instance link from the Manage Servers page
3
Click the Server Status tab
4
Click the Monitor Current Activity tab
5
Set the Monitoring Current Activity to ON to monitor the server
You can also refresh the server in following intervals 5,10 and 15 seconds and view the statistics
of the DNS, Keep-Alive, Cache, Server Requests and Work Thread connections.
Embedded DNS Resolution
The embedded DNS supports the non-default name resolution. The DNS client interacts with a
DNS server to perform the name resolution. The new SAF dns-lookup, receives the DNS
server's IP address as a server argument. This IP address should be added as a DNS directive in
the obj.conf file.
In the following example, IP of the DNS server is specified in the server parameter.
<object>
....
Release Notes for Sun Java System Web Proxy Server

Enhancements in Sun Java System Web Proxy Server Releases
DNS fn="dns-lookup" server="170.168.10.3"
...
</object>
In the following example, you can add multiple DNS server IPs to dns-lookup-init, and it will
be used in round robin model. In this scenario, do not add DNS server IP to dns-lookup. If
DNS server parameters are added to both dns-lookup and dns-lookup-init, the dns-lookup
argument will take the precedence.
...
<Object>
...
DNS fn="dns-lookup"
....
Init fn="dns-lookup-init" servers="170.168.10.3, 170.158.10.4"
</Object>
ACL Cache Tuning
The ACLCacheMax is a magnus.conf parameter that sets a limit to the total number of ACLs
stored in the ACL cache. There is no default value for ACLCacheMax and it should be configured
for a specific limit.
For example, ACLCacheMax 16384
Note – The ACL cache in this context does not refer to the ACL user cache. It refers to a cache
where ACLs are applicable to specific URLs that are cached for performance reasons.
The GCAtStartup is a magnus.conf parameter that allows boolean value. By default the value is
false, if set to true, Cache garbage collector clears the garbage during the server startup. This can
increase the server startup time when the cache size is high.
The New Directives in the magnus.conf File
This section lists the newly added parameters in the magnus.conf file.

TABLE 1
magnus.conf Directives
Parameters
Valid Values
Description
ACLCacheMax
1
Specify a configurable limit for the ACL
cache. This directive restricts the size of ACL
cache, thus removing old entries from the
cache which otherwise contributes
significantly to memory usage.
FtpPoolSize
1 – 65536
Specify the size of the FTP connection pool.
The default value is 256.
FtpPoolLife
1 – 65536
Specify the life of the connection in seconds,
that the FTP connection remain unused in
the pool before the monitor thread closes it.
The default value is 3600.
FtpPoolMonitorThread
OFF
Specify the boolean value to monitor the FTP
thread functionality. The default is ON.
FtpPoolMonitorLevel
0
Specify an integer value. If set to 0 the pool
monitor thread checks whether the
connection is dead or alive.
If set to 1, the NOOP command is sent to the
connection and awaits for the reply. Failure
to get a response will cause the connection to
be removed from the pool. The default level
is 1.
FtpPoolMonitorInterval
30 – 65536
Specify an integer value in seconds, after
which the pool connections are monitored.
The default value is 30
Cache PURGE Feature
Proxy Server allows PURGE requests to clear the cached URL. If the requested URL is purged
successfully, a response with an HTTP status code of 200 (OK) is sent by the server. If the
specified URL is not cached, a 404 (Not Found) response is sent.
In the following example, the server returns the value 200
bash-2.03$ telnet localhost 8088
Trying 172.9.10.1...
Connected to localhost.
Escape character is ’^]’.
PURGE http://foo.com/ HTTP/1.0
HTTP/1.1 200 OK

Daylight Savings Time (DST) will start in USA from the 2nd Sunday of March and end on the
1st Sunday of November. This will impact the date and time rules of the operating system and
JRE.
In the standalone version of proxy server, JRE version compatible with 2007 DST changes is
bundled with the installer. However, you need to address the impact on the date and time
rules of the operating system by installing the appropriate Operating System patches as
explained in step 1 of the Workaround.
For the JavaES 5 installation of proxy server, you need to install the Operating System patches
and also the compatible version of JRE . Follow steps 1 and 2 of the Workaround.
Workaround
1. Download and use the appropriate operating system patches. You can download the
Solaris patches from http://sunsolve.sun.com/search/
document.do?assetkey=1-26-102775-1.
For other platforms, download similar DST compatible patches from the Operating
System vendor's web site.
2. For Solaris, Windows, and Linux, run proxy server with JRE 1.4.2_13. For HP-UX, run
proxy server with JRE 1.4.2.12.

Doc RFE: Proxy Server should not be used with Network Cache Accelerator (NCA).
When the Proxy Server 4.0.8 is used with NCA, a browser repeatedly prompts for the User
ID and password. This happens because NCA does not support Proxy-specific headers like
Proxy-authorization.
Workaround
Do not select NCA in the Proxy Listen Socket setting.

Proxy Server 4.0.9 can be installed on OpenSolaris by using the GUI installer only if the
--javahome option of the setup command is used to specify a JDK 1.6 location.
6607551
On Windows, uninstalling the patch does not change the Proxy Server version to the
previous version number.
Reverting the patch through Uninstaller script does not change the service description
name to the previous Proxy Server version due to RenameService.exe utility limitations.
Therefore, even after uninstalling the patch, the service description shows the latest Proxy
version instead of the previous version number.
Internationalization

Starting the server in a different system encoding causes any errors returned by the system in
that particular system encoding to be logged in the error log. When viewed through the
Administration server, the error log might have characters in system encoding that do not
display properly.
Workaround
Change the browser encoding to match the OS locale so that the error log can be properly
viewed through the administration interface. But this will be needed every time you move to
other pages and then return to View Error Log again.
