Do you go through a proxy server ?
I don't know much about proxies, but could the proxy be turning off the gzip request ?
I have just been testing my browser at browserscope.org and it reported that my broswer did not support compression when I know it does. I go through a proxy here and wonder if that is causing the problem.
