i have some code into one of the include pages that is cleanning out the query string from unwanted characters, and after doing it's job redirects to the same page was supposed to go.

the problem is that if a form is submited i am loosing all sessions.

Is there anyway I could detect if a form is submit it without having to insert some sort of hidden fields values.
The website is running for sometime now, and there are a lot of pages which have forms into, so I am looking for a simple way out it there is one.

Thanks

I found the answer.

if Request.Form.Count = 0 then
execute the code
end if
