Only the first and third have the same URLs - the second entry is for a different URL. Based on your squid.conf and the access.log entries here, the third request should have been a TCP_HIT. It could be that the web server is sending a "Pragma: no-cache" HTTP header, causing Squid to not serve the request from the cache despite your refresh_pattern settings. Unfortunately, attemtping to test the URL with the Cacheability Test Engine results in a timeout, so I cannot verify this. AFAIK, there is no way to override "Pragma: no-cache" in Squid. If the server is indeed sending this header, then there is nothing you can do to force Squid to cache the update files. Adam
