I would like to know of a way to hide querystrings in a browsers address bar. I do not want anyone modifying a variables value by typing in the address bar. Such as the example for the message board:<BR>((www.aspmessageboard.com/forum/asp.asp?M=208&P=2&F=20#Input))<BR>Variables M, P, F can be modified, how can I prevent that?<BR><BR>Thanx.<BR>
