I am running squid 2.4 (not by choice), its part of my sidewinder firewall. Am having users complain because they cannot get to support.microsoft.com Found a work around that is good for 2.6 but wont work in 2.4 acl support.microsoft.com dstdomain support.microsoft.com header_access Accept-Encoding deny support.microsoft.com The header_access line isnt supported in 2.4 I am working on getting a separate (and newer squid online), but until then are there any rules I could apply in 2.4 that would solve my problem? Thanks in advance... Les F
