Antwort: [Mod_gzip] [ANNOUNCEMENT] mod_gzip 1.3.26.1a

Then I should either stick with the old version for now or exclude Netscape
4 with User Agent.  I think most corporations with proxy servers would use
only a few different browsers, so that should not be much of a problem.

Short and hard: no, there isn't.

Yes, you understood correctly.

Yes.
But this is really mandatory. If you set 'mod_gzip_min_http 1001' the
variant of the request depends on a condition you can not express with
HTTP. Therefore the 'Vary: *' is send.

header.

Right. Again, this is mandatory.

Not disable. It will make it hard to cache the request and the proxy has
to save lots of variants, but it should not disable it.
