A simple echo server that serves socket policy files

Later versions of Flash 9 and Flash 10 have much tightened security features that are extremely frustrating to get the hang of the first time when doing sockets programming. Here is a very straightforward and simple implementation of an echo server in Python that has been tested to work with versions all the way up to Flash 10.0.22.87.

This server also correctly serves socket policy files on the same port that you connect to, eliminating the annoyance of having a separate policy file server on port 843.
