Some web service clients will pass cookies properly. I believe that CF does this, so if you have your application set to use cookies with session management, your CF client should work fine. > Does anybody have any good pointers or reading material about suggested > methods to maintain state across web service calls.

If you want, you can build your own state management mechanism that would basically return a token on the first method call, then accept that token on subsequent method calls - basically just what cookies do, but an explicit value that would be passed as an argument to subsequent requests. But I suspect that most web service clients support cookies by default nowadays.
