# Originally from http://sharebear.co.uk/blog/2009/09/17/very-simple-python-caching-proxy/
#
# Usage:
# Stup localhost 80000 as proxy in web browser cache will cache the files
# on disc and not redownload it again.
# To clear the cache simply do a `rm *.cached`. To stop the server simply
# send SIGINT (Ctrl-C). It does not handle any headers or post data.
