I'm using Squid version 2.6 stable 12. When initially requesting the page http://ads1.msn.com/library/dap.js with Accept-Encoding: gzip, I get the response properly. At the second time, when requesting the same object with no Accept-Encoding header at the request, I get again, the compressed response internally from the cache. My browser is unable to parse this response. Can anyone advise?
