I have searched for the answer to this question in vain. Maybe someone here will know the answer. Is it possible to clear the request collection? (ie set all the values in it to null)<BR><BR>The reason I want to do this is because I have certain pages on my site set up so that they don't cache. I have set a flag on these pages to prevent duplicate information being sent to my database if a user hits the back button and then hits refresh. However I have found one way in which someone can avoid this flag, so I need to be able to destroy the values in the request collection before this method is employed thus negating it's effect.<BR><BR>Thanks for the help.
