Typically there's a session ID somewhere in the transaction that's used to retrieve all the appropriate state information. The state information is persisted (the fancy name for "written to disk") on every request and then retrieved on the next request. As you might guess, this adds significant overhead. It's particularly painful when you need to re-open and reposition database cursors.

Just as a question

How do you all manage state in the HTTP stateless environment? What is
state?

Happy new year
