Walter,
Thanks for this suggestion..
I previously posted saying you could insert the session ID in the URL, but have since found out that this doesn't work if the page is requested from a different IP address. If my previous (deleted) post appears on any servers - ignore it it's incorrect. I will go with Walter's solution or perhaps a database driven shopping cart.
Thanks,
Nick...

Hi Nick,.
From your post, I understand that you're building an e-commerce site which uses session state to store a user's shopping cart; and you're calling external payment service asynchronizely with a callback to your server code. In this callback, you need to clear the payment's user's shopping cart. Since your callback server code doesn't run in the session context of the user who is issuing the payment, you want find a way to access the user's session by a session id or user id, right? Please correct me if I've misunderstood anything.
I'm afraid the built-in session state manager will not be able to let you access an arbitrary user's session.
If you're using ASP.NET 2.0, I strongly recommend you to use the Profile API to store your shopping cart, which can be accessed using a user name.
The major difference between Profile and Session objects are:
1) Profile object is persistent whereas Session object is non-persistent.
2) Profile object uses the provider model to store information whereas Session object uses the In Proc, Out of Process or SQL Server Mode to store information. (Refer to http://download.microsoft.com/download/2/a/e/2aeabd28-3171-4b95-9363-2215062
5a6a5/ASP.NET%20Provider%20Model.pdf for more information about ASP.NET Provider Model)
3) Profile object is strongly typed whereas Session object is not strongly typed.
Profile also supports anonymous user, which is a nice feature for letting your user first surfing your site and adding items to his/her shopping carts without registering/login; only when he/she wants to check out, then you can redirect him/her to the registration page and migrate his/her profile.
I will post some related URLs introducing the Profile feature of ASP.NET 2.0:
