Features and Benefits
AppFlow for HTTP accelerates web-based applications over the
The patented Molecular Sequence Reduction (MSR) technology
enables WX Series platforms to deliver up to a 10-fold increase in
effective WAN capacity, providing immediate congestion relief for
all IP-based traffic, including TCP- and UDP-based applications,
while allowing businesses to avoid costly WAN upgrades. The
MSR algorithm recognizes repeated data patterns and replaces
WAN by enabling WX Series platforms to learn and cache objects
associated with URLs. Similar to MAPI and CIFS, HTTP submits a series
of sequential requests for web objects, requiring tens or hundreds of
round-trips between the client and server to build a web page. With
AppFlow for HTTP, the WX Series platform transparently caches
objects locally, resulting in much faster pages loads.
