What is the WCF equivalent of HttpContext.Current.Request.RawUrl?

You can get the endpoint currently targeted and the Uri for it by doing:

OperationContext.Current.RequestContext.RequestMessage.Headers.To

which I think is the same thing as:

OperationContext.Current.IncomingMessageHeaders.To

This is a System.Uri object, and I believe you can just get the OriginalString or PathAndQuery, or whatever parts you want from it.
