Subject DO NOT REPLY [Bug 25201] Provide Cache Purge operation
Date Mon, 18 Oct 2010 23:12:47 GMT

What you're talking about is a conditional request, which comes as standard in

Send a GET request with the header "Cache-Control: max-age=0". If the cache has
a cached entity, it will add a conditional "If-None-Match" or
"If-Modified-Since" header, to which your server responds with "304 Not
Modified" if the content has not changed, or "200 OK" followed by the new
content if the content has changed.

Any CMS should support conditional requests as a matter of course, as they
represent a significant performance improvement.
