In Silverlight (and thus Windows Phone development) a developer is not allowed, for reasons unknown to me, to edit or alter the Accept- Encoding HTTP header. More info here: http://msdn.microsoft.com/en-us/library/system.net.webheadercollection%28v=VS.95%29.aspx
As such it's not possible to add gzip to the Accept-Encoding header and get a compressed response. I've seen other server-side implementations provide a work around to this by also checking a custom HTTP header for Accept-Encoding values, such as X-Accept-Encoding. Is this something that Twitter does, I'm guessing the answer is no, but thought I'd ask otherwise Silverlight and Windows Phone dev's won't be able to request gzip'd requests.
