CACHE::useragent
       Overrides the useragent value used by the cache to reference the cached
       content.

SYNOPSIS
       CACHE::useragent AGENT

DESCRIPTION
       By default, cached content is stored with a unique key that consists of
       the Host header, URI, Accept-Encoding and User-Agent.  If the content
       is generated the same for multiple User-Agents, this command can be
       used to group various User-Agent values into a single group, thus
       minimizing duplicated cached content.

       CACHE::useragent 

	    * Overrides the useragent value used by the cache to store the cached
	      content.

RETURN VALUE
VALID DURING
       HTTP_REQUEST, HTTP_REQUEST_DATA

EXAMPLES
	This will put all MSIE based browsers into a single cache group.

	when HTTP_REQUEST {
	  if {[HTTP::header User-Agent] contains "MSIE"} {
	    CACHE::useragent "MSIE"
	  }
	}

	This will ignore all client user agents and put all clients into the
	same cache group.

	when HTTP_REQUEST {
	  CACHE::useragent "GENERIC-UA"
	}
