[mod_python] [SPAM] apache and mod_gzip

Hi,

Can any body tell me if it make yet sense to activate mod_gzip with 
apache 2.2 ?
after reading several threads about it, I wonder if output stream  
gzip-compression is already included as standard behaviour of apache 2.2.

But I did not yet obtained any compressed output, although my http 
client asked about it (Accept-Encoding: gzip,deflate)
With a http traffic spy (TCP Viewer), I see normal text flow towards my 
client, while I expected bin flow (something like "$@r_§! etc.... ." !).

thanks for any help.
