Instant reverse HTTP proxy from a Linux command-line

Question

There is a nice trick to instantly serve contents of a current working directory by HTTP locally:

$ python -m SimpleHTTPServer

This command launches HTTP server at *:8000, serving $PWD contents.

I'm looking for something similar, but for setting up a reverse-proxy.

Something like this:

$ instant-reverse-http-proxy --listen-on 'http://localhost:8000/' --proxy-to 'https://example.com/path'`

So that

$ GET http://localhost:8000/bar

would fetch https://example.com/path/bar.

Any clues?
