Heh, and what about contains Accept-Encoding, how do your think?

I know where you're going. :) They say that the spaces (%20) are not
there. Unfortunately, they just come through a Vary header. If it is
blocked via manipulation of headlines - we break internet and get a lot
of trouble.

Here the situation is slightly more complicated than it seems Joe.
Developers must write the correct Vary treatment, taking into account
today's reality. Unfortunately, they will not do it. Even given the fact
that correct processing greatly improves efficiency and makes cache
Squid what it actually should be - caching proxy. Of course, you can
just pay the team a few thousand dollars - and this will be done with
ease. However, I believe that such basic functionality must be
implemented by default.

It is enough that Squid does not support and will not support compression.
