Assume you roughly have a one-to-one between scripts and web pages. How do you write a script to display its own web page or efficiently invoke another script/page? Redirect is slow. Can you exec, i.e. can a cgi script exec another in it's own place? For example: Suppose you write a "login" script/screen in a cgi file, to display and verify (and possibly redisplay) a web page for login information. On successful login, you want it to set some cookies and invoke another script/screen. A redirect seems extremely inefficient. I find this situation pops up all over the place. How do other people deal with this? Just redirect?
