Thanks...this is the kind of input I was looking for. Obviously any type of measure has a countermeasure, and if it works on a browser, It would work in LWP ( or some other interface ). The addition of a timestamp into the hash calculation is an interesting one. We've already worked out a method of using dynamically generated form field names from a hash of the session key. Adding the timestamp purturbs it a bit, and keeps someone from keeping a session alive over a long period of time. dws++...thanks again.
