Hi, if we request an cached object that is expired trough squid in accelerator mode and record squids request to the webserver we see this: GET http://acceltest/library/img/online.gif HTTP/1.0 If-Modified-Since: Tue, 28 Mar 2006 07:29:00.GMT Host: acceltest User-Agent: lwp-request/2.01 Via: 1.1 acceltest (squid/3.0.PRE5) X-Forwarded-For: 192.168.1.2 Cache-Control: max-age=259200 the object on the webserver is unmodified so the webserver replies: HTTP/1.1.304 Not Modified Server: Microsoft-IIS/5.0 Date: Fri, 17.Nov.2006 14:24:18 GMT X-Powered-By: ASP.NET Cache-Control: max-age=60 Expires: Fri, 1 7.Nov.2006 14:25:18 GMT ETag: "086ed473952c61:154b" Content-Length: 0 Despite the new "Expires" squid receives, it still replies to the client request with the old Expires and max-age values for the object. Is this correct behavior? For the browser this looks like the object is stale and it will reload it from the cache for every subsequent request? Thanks & regards Thomas
