This is not good learning code and it is a lot of code—the whole script you showed the link for must be read to follow it—to review, especially since you aren't interested in a discussion of its quality. Understanding how it works might be good for you. Learning to emulate some of what it's doing would be bad for you.

Part of what you're asking for now, though you don't know it, is a prototypes, security, and webframeworks lecture. The first of which is easy enough to provide: Far More than Everything You've Ever Wanted to Know about Prototypes in Perl -- by Tom Christiansen.
