Shockro,

The danger is also in variables.  Pretend that I get you to click on this
link from within your custom intranet mail app.

http://intranet.example.com/mailbox.asp?action=forward&item=all&[EMAIL PROTECTED]

It would forward all of your mail to [EMAIL PROTECTED]  This would  work
because you already have a session with mailbox.asp.

Of course mailbox.asp is fake but you get the idea.
