POST in Silverlight

I have a WCF Service that I'm trying to develop in a REST-based fashion. Because of开发者_如何学JAVA this, I have an operation that requires a POST operation. I've noticed that Silverlight does not support WebHttpBinding. My question is, how can you do a POST in Silverlight to a REST-based service? Especially a service that takes an object as a parameter.

Thanks!

here is a blog where get and post to REST services are described.
