Hi, I’m trying build a squid server that can cache youtube request for a school. I’m using squid 3.4.7 compiled from source on Ubuntu server 14.04
I have a lot of request that are cached, but not served from cache and generate a TCP_MISS/200 I’m trying to figure why this requests are not served from cache. Please find attached squid.conf and cache.log sample with debug enabled. I hope someone can help me. Thanks Josep *************************************************** access.log ******************************************************************* 1412953551.775 167 192.168.1.112 TCP_MISS/200 4344 GET http://i1.ytimg.com/vi/9_iANxI-Mrc/default.jpg - ORIGINAL_DST/74.125.230.3 image/jpeg ****************************** cache.log ****************************************************************************************** ---------- 2014/10/10 17:05:51.772| ctx: enter level 0: 'http://ytimg.com.squid.internal/vi/9_iANxI-Mrc/default.jpg' 2014/10/10 17:05:51.773| http.cc(705) processReplyHeader: processReplyHeader: key '9F1BB8D27BED16A8B74F8995105B2941' 2014/10/10 17:05:51.773| http.cc(749) processReplyHeader: HTTP Server local=192.168.111.10:59210 remote=74.125.230.3:80 FD 65 flags=1 2014/10/10 17:05:51.773| http.cc(750) processReplyHeader: HTTP Server REPLY: --------- HTTP/1.1 200 OK Content-Type: image/jpeg Last-Modified: Thu, 01 Jan 1970 00:23:21 GMT Date: Fri, 10 Oct 2014 10:45:51 GMT Expires: Fri, 10 Oct 2014 16:45:51 GMT X-Content-Type-Options: nosniff Server: sffe Content-Length: 3861 X-XSS-Protection: 1;
