[Mod_gzip] Apache as a proxy server

[Porter, Mark]

I have a 1.3.27 server on Solaris running as a proxy server on our
internal network as a proof of concept. I can't seem to get compression
working, though.
 
Some details:
 
Apache 1.3.27
mod_gzip 1.3.19.1a
 
The end of httpd.conf:
 
# MOD_GZIP configuration
mod_gzip_on yes
mod_gzip_minimum_file_size  1002
mod_gzip_maximum_file_size  0
mod_gzip_maximum_inmem_size 60000
mod_gzip_item_include handler ^proxy-server$
mod_gzip_item_include mime "application/x-httpd-php"
mod_gzip_item_include mime text/*
mod_gzip_item_include mime "httpd/unix-directory"
mod_gzip_item_include mime "image/jpeg"
mod_gzip_item_include mime "image/gif"
mod_gzip_item_include mime "application/x-javascript"
mod_gzip_item_include mime "application/msword"
mod_gzip_dechunk Yes
mod_gzip_temp_dir "/tmp"
mod_gzip_keep_workfiles No
mod_gzip_item_include file "\.php3$"
mod_gzip_item_include file "\.txt$"
mod_gzip_item_include file "\.html$"
mod_gzip_item_include file "\.*"
#mod_gzip_item_exclude file "\.css$"
#mod_gzip_item_exclude file "\.js$"
 

LogFormat "%h %l %u %t \"%V %r\" %>s %b mod_gzip: %{mod_gzip_result}n

ProxyRequests on

What I'm seeing in the logs when I access sites through the Apache
proxy:
 
<Source IP> - - [16/Dec/2002:18:24:42 -0500] "spider.lmig.com GET
http://www.libertymutual.com/corp/lmss-ie5.css HTTP/1.1" 200 22612
mod_gzip: - In:- Out:-:-pct.
 
Any ideas?
