Including "header_access Accept-Encoding deny all" in squid.conf seems to do the trick.
However, checking what Internet Explorer vs Firefox sends:
Internet Explorer
-----------------
Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, application/x-shockwave-flash, */*
Accept-Language: en-us,nl;q=0.5
Accept-Encoding: gzip, deflate
Firefox/Mozilla
---------------
Accept: text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5
Accept-Language: en-us,en;q=0.5
Accept-Encoding: gzip,deflate
Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7
A quick glance shows that the only difference in the encoding header is _one space_. Thats all.
Any ideas what happens because of this ?
