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

No. Not using VFP client, just VFP XML web service.

>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 session variable stays alive for the life of the users session. With every method call to the web service, the contents of the session variable are passed to in along with any other parms. The web service method always authenicates user in another method before proceeding. If it fails, a false is returned and asp.net either redirects user back to login screen or a message is displayed.
