[Mod_gzip] mod_gzip + proxy

[Mikko Hakala]

Hi!
I would like to have all my "Internet traffic" to be compressed with
mod_gzip...
| INTERNET |-------|Server: Apache /mod_Proxy / mod_gzip|------ Slow
connection ------| Clients |

I'm using Apache/1.3.24 (Unix) and mod_gzip 1.3.26.1a.

It works when I get pages directly from my server.
GET /manual/install.html HTTP/1.1" 200 6288 mod_gzip:OK In:18076 Out:6288:
CompRatio:66pct.

...but when I use proxy and get pages from Internet...
I get the following log file:
GET http://lists.over.net/pipermail/mod_gzip/2002-November/thread.html
HTTP/1.1" 304 0 mod_gzip:- In:- Out:-: CompRatio:-pct.

Is there way to get it work?
