Play decast - Tunneling a PUT through POST with RESTful WCF Services
Many client technologies such as Silverlight 2 only support the HTTP Methods GET and POST.

In this screencast, Rob Bagby illustrates how to tunnel HTTP Methods such as PUT and DELETE through POST, as well as how to consume these services with Silverlight 2. This screencast illustrates some of the great functionality available in the WCF REST Starter Kit.
