When you see HEAD in your logs, AND squid does not cache, it could be from IE, checking freshness of cached video data. So, for a clean test for you: Clear IE's cache. Make shure, your squid has no cache and its mem cache cleared. Only difference then between our setups is, that I have transparent squid AND another version. Transparent should not be an issue. Is this the only embedded video, which does not work in IE ? -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/Squid-2-7-STABLE5-hangs-with-HEAD-request-in-LOG-tp4664219p4664222.html Sent from the Squid - Users mailing list archive at Nabble.com.
