Because I need shared state, 'Shared state' seems more like a derived requirement from your authentication mechanism choice and its implementation. You stated: ""Yeah, I know, it's not really without state, it's just that all the state is in the representations sent back and forth. Not good enough -- you need *shared state* that doesn't get communicated. Go see the SSL/TLS or WS-SecureConversation specs."" You need shared state. Shared state that doesn't get communicated. Shared state that doesn't get communicated over HTTP. And you claim that the 'statelessness' of HTTP is a problem. I must be mis-userstanding something because that is a real head-scratcher. To narrow the conversation, I'll go read WS-SecureConversation. > and because every > client operation ends up being a POST. Again, this seems more like a derived requirement from how the authentication and/or protocol was implemented, though at this point I have scant information to go on. Are there more detailed reasons as to why every client operation ends up being a POST? > The first > seems impossible, and the second means the framework > benefits are nil. Even if every operation is a POST, I believe there would be a benefit from leveraging the extensible authentication mechanism outlined in RFC 2617. The most obvious one of which is that it can be applied to resources who representations aren't just 'application/soap+xml', i.e. HTML, images, etc. Thanks, -joe -- Joe Gregorio http://bitworking.org
