[FX.php List] Security Concerns with FileMaker Website

[Jonathan Schwartz]

I have also noticed the bots because I am logging every arrival to my 
fx.php pages for development and customer support resaons.

In my solutions, I am using sessions. Without a current session, the 
page never gets past the session check on line 3.  The "user" is 
redirected to the start page to either log in or to start the process 
(whatever it is).

So, the bot might hit the page, but never sees data.

Works for me, but YMMV.

Hope that helps.
