Windows Phone ASP.NET Web Services Compression

I am developing an application for Windows Phone and iOS, and he needs to use the ASP.NET web service (SOAP developed by me). The amount of data that I upload through the web service is relatively large due to the inherent verbosity of XML. I would like to compress server responses to my SOAP calls using the IIS ISAPI compression module. On iOS, I use wsdl2objc, which works great. The Accept-Encoding: gzip,deflate header is present on calls from iOS / wsdl2objc. IIS properly compresses the answer that dandy works.

On Windows Phone, I use automatic SOAP wrappers, with a web service added as a Service Reference. It also (functionally) works fine. The application is functioning correctly, but the header sent by the generated code is Accept-Encoding: identity . I heard through the tubes that the generated code uses WebRequests that support gzip'd content.

Is there an acceptable way to add the Accept-Encoding: gzip header on the phone side or return a compressed Content-Encoding: gzip response from the server?

Thanks in advance!

Note. I am using the ASP.NET web service, not the ASP.NET WCF service.

It turns out that the main HTTP request request baked in WP7 SOAP has exactly 0 support for compressing GZIP / DEFLATE responses (or requests, for that matter). I am going to end up running my own SOAP class generator solution that uses WebRequest classes to do this.

Has WebRequest and WebResponse, which include support for GZip. Their latest update says that you can register it to work with ANY WebRequest, but I have not tried this part myself. Therefore, if the code does use a standard web request under the hood, you should be good to go.
