Sessions have been the latest addition to my project, and I've been doing a lot of research with them...
In my admin. panel, once a user logs in, session variables 'username', 'password', and 'department' will be set. For every administration page thereafter, I will check to see if those variables have been set. If they have not been set, I will re-direct them to a login page. Otherwise, if those variables have been set, administration pages should take their normal action.
Short and sweet logic, but is this the general idea?
TIA, Mike
