Stateful PHP Web Service Using SOAP
I'm trying to implement a stateful web service in PHP using the SOAP extension. (Yes I know that web services are supposed to be stateless; all I really care to persist is some form of a session ID so I don't need to authenticate with every call to the service).

Stateful Webservice
Possible Duplicate stateful webservices I have a need for a stateful webservice in our organization.

Because page isn't stateless, each request causes serialization of page. So far so good. But some of these AJAX requests doesn't change page ever, so serialization of ...
