Introduced in Edge Component V5.0.2 for Caching Proxy, the
UseSession option can be specified on the Proxy or ProxyWAS directive.
Sometimes servers expect that the requests for a page are transmitted on
the same TCP channel from the proxy, providing these requests are
submitted to the proxy on the same TCP channel. The UseSession option
helps to maintain a persistent channel on the server side if the requests
from a client are forwarded to the same server and from the same
client-side TCP channel.
The UseSession option overrides the directive ServerConnPool, which
allows requests from different clients to share a persistent connection to
the back-end server.
Following is an example of the UseSession option on the Proxy directive.
Proxy /abc/*
http://server1/default/abc/* :80 UseSession
Description: The Proxy rules pass requests (templates) to another server
(target).
If the incoming client request comes from port 80 and if the URL on the
client request matches the pattern /abc/*, the URL is mapped to http://
server1/default/abc/* .
For more information on mapping rules, refer to section "Define mapping
rules" in the Caching Proxy Administration Guide. |
