Sounds like (yet another) job for a Filter! I have a similar thing, a MaintenanceFilter that checks to see if the system is under maintenance, and sends the user to a so-sorry-try-later page. Letting them continue on is surely possible... Depends on what's in the request. Form fields are easy enough to handle with hidden fields, then the 'OK' button actually submits a new request, with an extra field that'll let you through the filter. I tend to solve this sort of thing by putting everything in session scope. -- Wendy Smoak Application Systems Analyst, Sr. ASU IA Information Resources Management --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
