Overview
SpeedCheck Java Applet checks the permission page (parameter: permission_url) everytime the user clicks the "start" button. The server-side script returns a flag (1 or 0) as plain text and tells SpeedCheck to start/stop functioning.
Usage example: we can query the raw data from database and tell SpeedCheck to stop working if an unique address has reached the daily transfer limit. In our online demo, we limit each user to have maximum 5 MB of transfer. If a user exceeds that limit, they will get an error message.
By default, this feature is turn OFF. It is optional for you to use this functionary.
Prerequisites

Permission by default is disabled. To enable it, open up /config/include.php and change the following:
