I suspect the culprit is the Range: header issued by the application. You should be able to configure squid to always download the while file anyway. Depending on the squid version, setting quick_abort_min -1 KB might work -----Original Message----- From: Donoso Gabilondo, Daniel [mailto:donoso.d@xxxxxxxx] Sent: Thursday, April 16, 2009 7:02 AM To: squid-users@xxxxxxxxxxxxxxx Subject: Squid doesn't cache some objetcs I resend this mail because I don't know if it arrived well the first time. (I have received it in the spam folder) If it was received well sorry for send it again. I'm using a linux application that uses squid to cache the objects. If I ask the objects with wget linux command the objects are cached well, but with the application it always receives "Partial Content" I saw that GET headers are different. The application adds to header a Range attribute (is this the problem?) The application header is this: GET /Resources/rsc/National/Diapositiva20.JPG HTTP/1.0\r\n User-Agent: Lavf52.16.0\r\n Accept: */*\r\n Range: bytes=0-\r\n Host: myserver.com:8080\r\n Authorization: Basic\r\n Via: 1.1 localhost.localdomain (squid/3.0.STABLE13)\r\n X-Forwarded-For: 127.0.0.1\r\n Cache-Control: max-age=0\r\n Connection: keep-alive\r\n And the wget header content: GET /Resources/rsc/National/Diapositiva20.JPG HTTP/1.0\r\n User-Agent: Wget/1.11.4 (Red Hat modified)\r\n Accept: */*\r\n Host: myserver.com:8080\r\n Via: 1.1 localhost.localdomain (squid/3.0.STABLE13)\r\n X-Forwarded-For: 127.0.0.1\r\n Cache-Control: max-age=0\r\n Connection: keep-alive\r\n Best regards, Daniel
