If the _whole_ content of the application and it's semantics can be derived from RFC 2616, then yes. HTTP semantics are visible to HTTP intermediaries. But as acres of earlier mail should have made clear, I don't believe that the semantics of Web services can be fully captured at the level of HTTP. Let's face it, HTTP isn't even enough for plain hypertext ... the HTML REC isn't an appendix of RFC 2616 ;-) Cheers, Miles
