>>9 No no. The entire site is made in such a way that it redirects you to the login screen if you don't have the correct password stored as a cookie, or temporary internet file.
Generally, the password will be "forgotten" by your computer after a while of being logged off, though I'm not entirely clear on how that works. As long as you stay logged in and moving about the site though, the timer refreshes and you will be able to navigate the entire site just fine.
It's really about 1 line of code to include the "requires password cookie" bit. All it is is a conditional check, and a redirect if necessary.
