.NET WCF Can't Decode "Chunked" response.

Question

I am calling an axis web service from WCF. The request works just fine but I get back null values. Using Fiddler I was able to determine that the response is coming base as Transfer-Encoding: chunked. This means that there are control characters in in the response BEFORE the xml. WCF does NOT throw an error. It just moves on and the object that is supposed to be returned by the Method is null. Can anyone tell me how to tell WCF how to correctly handle an HTTP 1.1 chunked encoded message?

Here is a link to someone asking a similer question:

I don't think you will be able to get that to work as IIS (or the client depending on what side you are on) should strip that out before it gets to you, same as you should not have to manually de-gzip a request.

In this case it seems that chunked is not well supported by server software.
