Handle external files

How can I handle external files? I like to create external databases for my games, like enemies, items and maps, all in arrays. How can I access this once my game is online? Will AppPath work in this case?

There's no file system available for javascript (at the moment).

To handle those kind of things you need to go through ajax calls and online database hosting.
