This application is meant as a "Sit and do it all at one time" application. I don't care about the cookie after the user enters his data 20 or 30 times and prints the final formatted page. The page is submitted to a higher beaurocracy than I for verification anyways. I am just looking to save several hundred people an hour's time each month in authoring mileage reimbursements. I want to get away from flipping thru several pages of "official mileage reimbursement distances" and just have people enter data one trip at a time and have the math done for them. I want it dated for each trip, in such a way that they specify what day of the month they made the trip. Thanks all for the insight into cookies, size limits, etc.

Maybe someday I will incorporate authentication, stored databases of user mileage, higher security and the rest, but for now all I need to do is get the data to flow properly from query to query.
