Hello. I have an Squid proxy cache configured as frontend of a Coocoon server. The problem is I always get a TCP_MISS. Here is an example of two clicks (2 seconds between them) over the same link: 1183027652.407 320 10.240.216.71 TCP_MISS/200 16870 GET http://intranet.juntadeandalucia.es/cocoon/aj-ic--.html? - DIRECT/10.240.230.117 text/html [Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/x-shockwave-flash, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, application/ag-plugin, */*\r\nReferer: http://intranet.juntadeandalucia.es/cocoon/aj-ic--.html?language=es\r\nAccept-Language: es-us\r\nUA-CPU: x86\r\nAccept-Encoding: gzip, deflate\r\nUser-Agent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR 1.0.3705; .NET CLR 1.1.4322; Media Center PC 4.0; InfoPath.2)\r\nHost: intranet.juntadeandalucia.es\r\nConnection: Keep-Alive\r\nCookie: JSESSIONID=9CCBB0416097222564AD68866D57C8FE; JSESSIONID=E3FA7D4B02D083709C0DEB659D3EC470; JOSSO_SESSIONID=78CEE222AC6B0E58E2EF00F50CAEC8FD; AWSTAT_USER_ID=josej.sianes.ext; cocoon_int=f41d5ccbf41d6375a52ebb49\r\n] [HTTP/1.1 200 OK\r\nX-Cocoon-Version: 2.1.7\r\nVary: Cookie\r\nVary: User-Agent\r\nExpires: Thu, 28 Jun 2007 10:57:32 GMT\r\nCache-Control: max-age=600, public\r\nContent-Type: text/html\r\nDate: Thu, 28 Jun 2007 10:47:32 GMT\r\nServer: Apache-Coyote/1.1\r\nConnection: close\r\n\r] 1183027654.828 386 10.240.216.71 TCP_MISS/200 16870 GET http://intranet.juntadeandalucia.es/cocoon/aj-ic--.html? - DIRECT/10.240.230.117 text/html [Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/x-shockwave-flash, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, application/ag-plugin, */*\r\nReferer: http://intranet.juntadeandalucia.es/cocoon/aj-ic--.html?language=es\r\nAccept-Language: es-us\r\nUA-CPU: x86\r\nAccept-Encoding: gzip, deflate\r\nUser-Agent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR 1.0.3705; .NET CLR 1.1.4322; Media Center PC 4.0; InfoPath.2)\r\nHost: intranet.juntadeandalucia.es\r\nConnection: Keep-Alive\r\nCookie: JSESSIONID=9CCBB0416097222564AD68866D57C8FE; JSESSIONID=E3FA7D4B02D083709C0DEB659D3EC470; JOSSO_SESSIONID=78CEE222AC6B0E58E2EF00F50CAEC8FD; AWSTAT_USER_ID=josej.sianes.ext; cocoon_int=f41d5ccbf41d6375a52ebb49\r\n] [HTTP/1.1 200 OK\r\nX-Cocoon-Version: 2.1.7\r\nVary: Cookie\r\nVary: User-Agent\r\nExpires: Thu, 28 Jun 2007 10:57:34 GMT\r\nCache-Control: max-age=600, public\r\nContent-Type: text/html\r\nDate: Thu, 28 Jun 2007 10:47:34 GMT\r\nServer: Apache-Coyote/1.1\r\nConnection: close\r\n\r] As you can see, the second click get a TCP_MISS when the expiration date is obvious not expired yet (max-age=600, 10 min). Why Squid is not making a HIT? Any comment will be very appreciated. I'm using Squid 2.6 version.
