I am creating a login script which 1)has the login in form 2)then calls an external script to check the user name and password and 3)then goes back to the original or into the logged in page depending on the un/pw check. My question is how do I do a redirection from the external script back to the other script(s) and PASS PARAMETERS? I need to pass the sessionID mainly. I also need this to be safe so I'm not sure what the safest way is: a cgi redirection or a system call (I'm not very skilled in calling a script within a script, I've only done this a couple times)? Either way, how do I pass the parameters? And, I really don't want any information like the sessionID displayed at the top of the browser address bar (like the paramers). Any suggestions?
