My nginx conf:

gzip on;  
gzip\_http\_version 1.0; #if I leave this line out, i am not passing  
GIDZipTest, but firefox is getting gzip if connected outside my company  
LAN  
gzip\_vary on;  
gzip\_comp\_level 1;  
gzip\_proxied any;  
gzip\_types text/html text/css application/x-javascript text/xml  
application/xml application/xml+rss text/javascript  
application/javascript ;

TEST:

curl -I --header ‘accept-encoding:gzip’  
[zagreb-test.12ip.net/stylesheets/base\_packaged.css](http://zagreb-test.12ip.net/stylesheets/base_packaged.css)

> From my company intranet:

curl -I --header ‘accept-encoding:gzip’

There is no Content-Encoing header and .css is not gziped.

To make thing more interesting if I try to fetch googe cdn ui-css(it is  
compressed but I don’t he the gzip in the response)

(from intranet)

curl -I --header ‘accept-encoding:gzip’  
[http://ajax.googleapis.com/ajax/libs/jqueryui/1.7.0/themes/smoothness/jquery-ui.css](http://ajax.googleapis.com/ajax/libs/jqueryui/1.7.0/themes/smoothness/jquery-ui.css)

The Via header suggests you have some kind of proxy in the ‘company  
intranet’ .. it could be possible that it is either stripping gzip  
headers  
or maybe has non-compressed object allready cached and returning it.
