Hi. I'm using squid 3.1.16, compiled from source with: ./configure --prefix=/usr/local/squid-3.1.16/ --enable-useragent-log --enable-referer-log --disable-ident-lookups --with-large-files Running on a 64bit Debian 6 box. If I send a request: Sent by doing: cat file | nc proxy.example.com 80 ============================================================================== HEAD / HTTP/1.1 Host: www.example.com User-Agent: Mozilla/5.0 (X11; Linux i686; rv:7.0.1) Gecko/20100101 Firefox/7.0.1 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip, deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Cookie: eplicaWebVisitor=-926431977; fptab=skjalftar; JSESSIONID=C44066454BC7A2C8A052BC0C69D44620 DNT: 1 Connection: keep-alive If-Modified-Since: Sat, 30 Oct 2011 16:42:36 GMT Cache-Control: max-age=0 If-None-Match: S-is-94659-1319906578198 ============================================================================== I get back: ============================================================================== HTTP/1.0 200 OK Date: Mon, 31 Oct 2011 18:22:45 GMT Set-Cookie: JSESSIONID=05358DBC68CE264A981D34FB8322CADC; Path=/ Powered-By: Eplica WMS 2.0 (2.0-SNAPSHOT) Last-Modified: Mon, 31 Oct 2011 18:22:21 GMT Expires: Mon, 31 Oct 2011 18:22:55 GMT Cache-Control: public, must-revalidate, max-age=10 ETag: S-is-94983-1320085375761 Content-Type: text/html;charset=UTF-8 Content-Language: is-IS Vary: Accept-Encoding Content-Encoding: gzip Content-Length: 18425 X-Cache: MISS from proxy.example.com Via: 1.0 proxy.example.com (squid/3.1.16) Connection: keep-alive ============================================================================== If I send the same request, but leave out the "If-None-Match", I get: HTTP/1.0 200 OK Date: Mon, 31 Oct 2011 18:24:10 GMT Powered-By: Eplica WMS 2.0 (2.0-SNAPSHOT) Last-Modified: Mon, 31 Oct 2011 18:23:22 GMT Expires: Mon, 31 Oct 2011 18:24:20 GMT Cache-Control: public, must-revalidate, max-age=10 ETag: S-is-94983-1320085460159 Content-Type: text/html;charset=UTF-8 Content-Language: is-IS Vary: Accept-Encoding Content-Encoding: gzip Content-Length: 18425 Age: 3 X-Cache: HIT from proxy.example.com Via: 1.0 proxy.example.com (squid/3.1.16) Connection: keep-alive ============================================================================== Hmm... I *think* the needed lines from squid.conf would look like, but please correct me if this is not enough to determine the cause: http_port 1.2.3.4:80 accel defaultsite=www.example.com vhost ignore-cc cache_peer 1.2.3.99 parent 80 0 no-query originserver name=myAccel Now, is there a simple(ish) way of throwing away / ignoring that "If-None-Match" header, or configure squid in other ways, to go to the cache, and create a HIT? Thanks, -- EinarI
