I wanted an HTTP(S) proxy on Google App Engine, because apparently you can get rotating IPs for outgoing traffic automatically. Well it doesn't really rotate but actually just not guaranteed to stay stay static. Worth a try anyway.
Originally wanted to implement a proper generic proxy but gave up fast because while plain HTTP is easy, HTTPS requires actual tcp tunnelling which I'm not really up for at the moment (is that even possible on GAE standard evironment?).
So I devised my own "scheme". Dumbest thing that works right?
