Ah, well you seem to have all the settings needed to trigger a bug in
Apache. Start by trying with this option to let squid ignore it:
http://www.squid-cache.org/Versions/v2/2.6/cfgman/broken_vary_encoding.html

If the problems remains it may be a bug in squid and we shall test it
further.

Thank you.
