Caching Proxy: Using of MapQuery directive

Before the MapQuery directive was added, when the Proxy performed rule mapping, it always simplified the incoming request to a request path without the question mark. The Proxy also used the request path to match the mapping rules defined in the ibmproxy.conf.

In order to handle a URL with a query string, the MapQuery directive was provided. The functionality of the directive is almost the same as the Map rule, except it uses the whole incoming request (including the path and query string) URL to match the rule. If the incoming URL is matched on a MapQuery rule, the translated URL is used to match against the rest of the rules.

The following is an example. Assume the incoming URL is:

/getsomthing?type=1

Rules are the following:

MapQuery  /getsomething?type=*  /gettype/*

Proxy  /gettype/*  http://server/gettype/*

Note: The translated URL is now http://server/gettype/1.

MapQuery could also translate a URL with a query string to another URL with a different path or different query string. However, because all other mapping directives use request path, the changed query string is appended to the translated URL when the request path is matched.
