BTW, I am using POST just because there is no restriction on the length of the query string which I am passing to the cgi script. I read that GET has a max value but POST does not. Am I right? I have no reservations against using GET but only because it has max length. My query string can be way too long that's way I am using POST. --Ankur Where does the family start?
