15. I think when you say you'd like it to "refresh", you actually mean you don't want the pages to be cached (forcing the browser to contact the server everytime, thus always drawing the newest, up-to-date page).
This can be done with a simple HTML Meta tag:
<META HTTP-EQUIV="Pragma" CONTENT="no-cache">
Beware though, this doesn't work on all browsers.
Instead, you might want to send "Pragma: no-cache" along with the "Content-type: text/html" header within all the CGI scripts. This should work regardless of browser type (although I've heard that some proxy servers don't honor "no-cache" pragma's... but there's nothing you can do about that).
Preventing pages from caching should do what you're asking, but it's also going to increase your bandwidth usage.
