Ensure that your web app is sending the correct Expires: and Cache-Control: headers to enable caching for the 30 second period or however long you want. The cacheability engine is useful to identify exactly what is or not cacheable and why. http://www.ircache.net/cgi-bin/cacheability.py Amos -- Please be using Current Stable Squid 2.7.STABLE6 or 3.0.STABLE14 Current Beta Squid 3.1.0.7
