RE: [squid-users] Squid & HTTP compression

Amos thank you
I managed to find a solution to my problem!

I 've used the
broken_vary_encoding

And also changed this values on iis metabase xml

HcNoCompressionForHttp10="FALSE"
HcNoCompressionForProxies="FALSE"

This is a HIT. An earlier stored copy saved from some other client request.
I guess you are hitting a case of bad variant labeling, and the stored copy
is an old one with no encoding.
   Note how there is also no Vary: header which tells Squid to look at the
encoding type when re-using this response.

In 2.7 you need to turn on broken_vary_encoding feature and tell it that
this server or website is broken.

That or you are using header_access to wrongly remove things.
