PERL Backends for Gamemaker HTML5

The following may be applicable to non-gamemaker tasks, however I am writing from the point of view of a Gamemaker user so any HTTP communication will be instigated by the Gamemaker Asynchronous interface.

Security considerations

I'll cover this better elsewhere but please remember that you may be forced to fall back on "security through obscurity", so it is important to limit the damage that can be done by a simple attack. 

Online high score table

This is my first attempt at a backend script for GM HTML and I'm pleased with how it turned out

• The high score table consists of 20 entries, the top 10 are "all-time" and the next 10 expire after a time currently 8 weeks
• The script supports multiple games
• The new score and name are passed as CGI Parameters
• The score table is returned as a JSON encoded data structure
• The scores are stored in a file in simple text format, easy to back-up or clean up
• There is currently no word filter
• No database is required, this is intentional

At this time I'm not entirely happy to share the program as in its present form it is rough, but I would be willing to cooperate with anyone who wants to use it.
