Hi there, I usually test at the top of the page that does my 'logging-in' to
see if the variable I set for each user once they actually login is set.
So if I set a variable called '$isloggedin' upon a successful login, I would
check at the top of that page to see if it is set or not, if it's already
set bypass the login and redirect them to a new page.
