>I don't read the session variable from VFP web service. The contents of these variables (username and password) stay alive during entire user session in asp.net client application. Before any method call to web service, asp.net client store contents of session variables to string and passes them along with any other parameters to web service method being called. This way the web service has what it needs to authenicate user before running method code.

So, basically, you just pass them as parameters to every method you have. Such as this:

lcString=MyService.MyMethod(lcUsername,lcPassword,lcParamMyMethod1,lcParamMyMethod2...)
lcString=MyService.MyMethod2(lcUsername,lcPassword,lcParamMyMethod21,lcParamMyMethod22...)
lcString=MyService.MyMethod3(lcUsername,lcPassword,lcParamMyMethod31,lcParamMyMethod32...)

I was wondering how you were making use of the session object without using low level at the server end. :)
