I am trying to send an xml document to a REST web service. Using a tool like Poster, the call works fine (With the xml in the body of the "content"), but in my code, I get error 503 server unavailable.

My code is as follows (this is a test-harness so no error handling etc):

This does not work. Any ideas? Also, how do I achieve the same thing with webclient?
