このmodはApache用だと思います
http://httpd.apache.org/docs/2.2/mod/mod_deflate.html (2)
そして、これはNginxの場合
http://wiki.nginx.org/HttpGzipModule (1)
使用するサーバーに応じて、必要なもののように思えます。後は君しだい!
nginx モジュールは両方とも解凍をシャットダウンできることに注意してください。
[edit] gzip
Syntax: gzip on | off
Default: off
Context: http
server
location
if in location

Enables or disables gzip compression.
そしてプロキシを扱う:
[edit] gzip_proxied
Syntax: gzip_proxied off | expired | no-cache | no-store | private | no_last_modified | no_etag | auth | any ...
Default: off
Context: http
server
location
Reference: gzip_proxied
It allows or disallows the compression of the response for the proxy request in the dependence on the request and the response. The fact that, request proxy, is determined on the basis of line "Via" in the headers of request. In the directive it is possible to indicate simultaneously several parameters:
off - disables compression for all proxied requests
expired - enables compression, if the "Expires" header prevents caching
no-cache - enables compression if "Cache-Control" header is set to "no-cache"
no-store - enables compression if "Cache-Control" header is set to "no-store"
private - enables compression if "Cache-Control" header is set to "private"
no_last_modified - enables compression if "Last-Modified" isn't set
no_etag - enables compression if there is no "ETag" header
auth - enables compression if there is an "Authorization" header
any - enables compression for all requests

幸運をお祈りしています!
