Caching Proxy support for additional Proxy rule options
 Technote (troubleshooting)
 
Problem(Abstract)
Additional options are available for the Proxy or ProxyWAS rule.

Caching Proxy provides directives that require additional pattern matching at runtime. To improve the Caching Proxy performance, you can use these directives as options in the Proxy or ProxyWAS rule.

The minimum release levels that support this directive are: 4.0.2.57, 5.0.2.36, 5.1.1.10, 6.0.2.0
 
Resolving the problem
Use the following additional OPTIONS at the end of the Proxy or ProxyWAS rule:
USESESSION
This option instructs Caching Proxy to maintain a one-to-one mapping between the client-side socket and the outgoing socket. This option is useful for some applications, such as connection-based authentication, that need the proxy to keep the server-side socket alive and reuse the socket for the requests coming from same client-side socket.

NOCACHING
If the proxy rule is matched, this option instructs the proxy not to cache the corresponding responses.

NOCACHEONRANGE
If the proxy rule is matched and there is a Range header in the request, this option instructs the proxy not to cache the corresponding response.

NOJUNCTION
Use this option if the junction rewrite plug-in is enabled. This option does not allow the proxy to rewrite the corresponding responses if the incoming URL is matched.

JUNCTIONPREFIX:/prefix-string
Use this option if the junction rewrite plug-in is enabled. Instead of inferring the junction prefix from the first URL pattern in the proxy rule, the option explicitly declares the junction rewrite prefix.

Syntax:
Proxy  incoming-url-pattern outgoing-url-pattern [server]:[port]  [USESESSION | NOCACHING | NOCACHEONRANGE | NOJUNCTION | JUNCTIONPREFIX:/prefix-string]

Example:
Proxy   /test/*   http://server.com/test*   :443   USESESSION
