you could store the data in a cookie on the user's pc, or create a 
dictionary and store it in a temp_folder (stored in ram, not persistant). 
The dictionary would only work if you had a reliable way to identify a 
returning user (ie. do they log in with an ID that you could use as the 
dictionary key?).
