Web service requests are just HTTP POST requests containing a SOAP envelope as the request body. So, if the HTTP client in question (or, more exactly, the program someone wrote that uses HTTP and SOAP) can read cookies from the initial response and send those cookies on subsequent responses, you're all set, and you can use session variables just like you would with regular browsers and HTML pages. But if you don't want to depend on whether SOAP clients will return cookies, you can require that all SOAP clients call a login or initialization service, which can return a token of your choice. You could then require that token as an argument to all the other services you're exposing, and that would be used to associate that client with a "session" of some sort. What sort that would be, is up to you.
