acces restriction from variable

Newbie qustion. Is it possible to restrict access to a file this way:
a. User MUST access through file 1. File one has a variable that
b. the restricted file (file 2, in another directory) request from file 1 in
order to allow acces to it.

File 1 is just a redirect file generated from a successful post, but with
the required variable which file 2 has to recognize, otherwise not allow
access to it.

Possible?

Of course that's possible. What you'll need to do is us $_SESSION variables.
File 1 will set the variables while File 2 will read. File 2 will ask if a
specific
$_SESSION variable has been set, if not, no access is granted.

Just add session_start(); at the top of both files and you're ready to go.
