How to set the Expect header in Silverlight 4.0 to ignore HTTP status code 100

Question

I want the Silverlight 4.0 client to ignore '100-continue' response code from a RESTful resource service, to do this i need to be able to set the Expect header - ' Expect: 100-continue' is this possible with the HttpWebRequest class?

All the normal ways of doing this are not supported in Silverlight 4.0.

Answer 1

Can you look at the Silverlight security policy? You have to add the "Expect" header to the list of allowed headers in you clientaccesspolicy.xml. Give that a try.
