And what shows in the access.log when you fetch this object? The response headers are missing couple things. Also you are using a heuristic refresh_pattern that should not work and it's wrong to use such. The first thing is to change the refresh pattern to something more connected to reality rather then science fiction. refresh_pattern -i \.(jp[eg]{1,2}|pdf|gif|pn[pg]|bmp|tiff|ico|swf|css|js|ad|png)$ 1800 80% 7200 Try It and see if it changes something. And a refence for the available options that can be used with enough details to start to understand what you are doing: http://www.squid-cache.org/Versions/v4/cfgman/refresh_pattern.html In this specific case there is a cache server.. Oracle at the other side and the logs are the only one which will give us a glimpse into what is going on for real.

Squid does not modify or add them (unless you tell it to do that). The origin server does not honor the bogus "none" content coding requested by the client.
