Description:
I have a custom client that does not want to receive gzipped data. It specifies so in the HTTP request header as such:

Accept-Encoding: identity;q=1.0, gzip;q=0, *;q=0

When requesting http://en.wikipedia.org/wiki/Benzatropine, I still receive a gzip encoded page. The client is using Apache's HttpClient java library. Perhaps this is some kind of caching issue? Here is the full request and response headers.

The same problem happens when gzip is simply omitted from the Accept-Encoding as follows:

Accept-Encoding: identity

I specified gzip as q=0 in the above header in an attempt to be more explicit about what encoding I wanted. This did not make a difference.
