>When asp.net application starts, login form appears. When user attempts login his username and password are passed to a method on VFP web service which returns a true\false indicating sucess or failure. If true, username and password are stored to a session variable and used for each trip to web service.

From an ASP.Net client, you are able to establish session variables. Were you able to convert that into a VFP client?

I assume this is passed automatically in the header that you read from the server side. If you are not using a low level API, how are you getting access to the Session object?

The only way I have found on the server side to obtain the Session object is to use low level API. That is launched from the ASP listener. So, I am able to benefit of all my Web Service methods with that approach. However, This.oSession.SessionID returns a different session ID for every hit. That's the first problem. Secondly, even if I do This.oResponse.Cookies('Username')='Test', this doesn't seem to make it on the client side. I assume that approach is not practical. From what I've read, it seems we have to establish a server attribute on the WSDL side. There is no example on that on the net I have found. The only samples I have found where session object is used is from .Net on the server side where you can store that on the line prior to the method.
