Hi Sunnel
We track sessions in 4 ways.

1. Cookies
2. URL Rewriting.
3.Client Authentication.
4.Hidden form Fields.
Depending on the requirment,keeping in mind the security part the required one is selected.
e.g...
When u r working on a B2B portal u need to know the clients list and also vendor's list.Different screen's for different login.which can bo done by Client Authenticationi.e...by his ID & password.

URL Rewriting is a method used to track sessions when the browser being used by the client does not support cookies.In this process, all links and redirections during the client session must be encoded to include session ID as part of the URL.
Hope this helps
