Lost soul, needs help!

Q1. How to easily sort a scalar not by its key, but by two of its fields alphabetically?
example:
$SCALAR{‘key’}[0]  -- as last name
$SCALAR{‘key’}[1]  -- as first name

[download]

Q2. Is it possible to detect if a request came from a browser refresh? Because in my program by pressing the browser back button until just before the login form, a user that has been sign out, can sign in just by pressing the refresh, it would seem that the user name and password from the sign in form are being resent.

Thank you!!
