[Phpmyadmin-devel] Gzip HTTP Content-Encoding patch

[jeremy brand]

Hello Tobias (and others),

I've got board and decided to check up on this probject.  I was looking at
the feature request page on the sourceforge project and decided to whip
this out as I have just done a similar upgrade on my own web site and have
seen enourmous speed increase from the site.

I wouldn't recommend using it if the site is heavily loaded (imagine 50+
gzips running on your websever) but if it is only a single machine and
only the admin is accessing this, it should be fine.

It would be nice to know how much gzip increases the load on a heavily
loaded server, but I have no such server.

cioa,
Jeremy
