*Note* You don't need to use session_register() if you use $_SESSION.
In fact this probably isn't even doing what you think it is. Using
$_SESSION indexes is the preferred way to go about using sessions.

The __destructor() method is supposed to be about killing the class
(Request). It's probably bad practice to be changing $_SESSION vars
inside of there even if that $_SESSION var affects your class. Here,
read this page and maybe it will make more sense to you:
http://php.net/manual/en/language.oop5.decon.php
Heck, look at the user contributed notes since one of them will directly
affect this idea of yours.

If the reference count for $req is greater than 0 (i.e. there is a
Singleton) then __destruct won't be called. And why should it be
called? Because, again, __destruct is for cleaning up the class while
the object is getting destroyed.
