in reply to CGI application

Small tidbit: You probably don't want ?uid=tom&pwd=uy877 to show up in your url. It's unsafe for many reasons. Don't use GET when you're dealing with sensitive informatino or changing databases. Use POST.

    From a security point-of-view POST and GET are more or less the same. While it is true that POST doesn't show information via the URL, it exposes the same information as a GET in the actual network communication. Some would say using usr/pwd over http is completely unsafe. If security is an issue you better use https, sufficient for most purposes.



      Absolutely true. I hadn't considered man in the middle or arp poisoning type attacks where the intruder will actually see the payload of the packets.

      However, what POST protects against is for instance if a website uses a form to reset a password "". Any bored teenager can get unsuspecting users to click a link with that hyperlink embedded and reset that user's password. Obviously there are more dangerous examples than what that one, but it is this type of "attack" that POST will prevent in that the action is not present in the url.
