Hi Jerry,

From your description, I understand you want to programmatically restore a
certain session connection or forms authentication connection in your code
(by supplying the sessionID or authentication info) , correct?

Based on my understanding, for forms authentication, it is quite easy to
regenerate the authentication state, you can simply call the following
method to make the current user be authenticated again(supply the username):

FormsAuthentication.SetAuthCookie(username, true);

However, for session state, it is always done(validate client cookie) by
the built-in session state module. If you put the session state info(such
as ID) in querystring, runtime will not know it.  You can try manually add
the cookie (that contain the sessionID you previously stored) into ASP.NET
response.

If this not work, you may have a look at creating a custom
SessionIDManager, that can help you add your own code logic to read and
generate sessionID:

Hope this helps.
