I recently wrote a webservice to be used with Silverlight which uses the ASP.net membership and roles.
To validate the client in the service I look at the HTTPContext.Current.User (Which works when the service is called from Silverlight)
However, I've been trying to call the same service from an asp.net postback. But when I step-thru to the service the HTTPContext.Current has an emplty string for the username.
I'm guessing there is something that I'm not doing in the web.config file which is causing the httpContext to not be sent through the proxy to my service?
Any ideas would be appreciated. I need to be able to validate the client somehow using asp.net membership and roles and have it work from both an asp.net client and a silverlight client.
