Antibot

This aims to explain and perform an example of how the Client-Puzzle-Protocol (CPP) may be implemented (almost) entirely in HTTP. Side Note: I’m _mattata on Twitter, you should give me a follow. I do stuff like this often. The Client Puzzle Protocol at a high level is a way to slow down automated bots crawling a site so that they approach the speed that humans would normally browse your site. The bots are slowed down by requiring them to solve a “puzzle” or show “proof of work” in order to obtain a secret that allows them to continue to access the site.
