Caching files by partial URL

Items can be cached based only on a specified (significant) part of the incoming URL, instead of the full URL. This is useful in transaction-model Web serving or for dynamic caching, because the same response is often returned for varying incoming requests when significant parts of the incoming requests' URLs are identical.

You cannot use the Configuration and Administration forms to specify caching based on partial URLs. Instead, use the SignificantUrlTerminator directive in the proxy configuration file to specify a terminating code for URL requests. This specification causes Caching Proxy to evaluate only characters before the terminating code when it processes the request and determines whether the requested file is cached. When more than one terminator code is defined, Caching Proxy compares incoming URLs against the terminator codes in the order in which they are defined in the ibmproxy.conf file. See SignificantURLTerminator -- Specify a terminating code for URL requests for more information.
