Geen installatie nodig...
Het bestand met een willekeurige bestandsnaam plaatsen op een webserver met php/mysql en het werkt.
Ook je Javascript moet aanstaan.
Het loginsysteem gebruikt (zoals je ziet) sessions.

Let wel dat alle SQL-instructies werken, dus ook DROP, ALTER, DELETE, kortom alle mogelijkheden die MySQL ondersteund, pas hier dus mee op!!

Het script is werkend getest in IE 6.0 en FireFox 1.0.7!

Code:
willekeurigebestandsnaam.php
