Gzip HttpWebRequest

Question

I am sending HTTP POST requests through HttpWebRequest which contain a lot of content. I would like gzip message content. Is it possible?

Do I need to configure IIS 7 to handle compressed content? It is already configured to serve compressed responses.

I tried adding the Content-Encoding = gzip header and writing it to the request stream wrapped in GZipStream, but the server returns 504 (GatewayTimeout), which seems odd.
