Pretty URLs in Google App Engine

Question

I want to pass a parameter 'A1B2C3' to a GWT application based on Google App Engine. I do it like www.example.com/index.html?key=A1B2C3. Although it's working, I'd like to use pretty URLs. Is it possible to do URL rewriting on Google App Engine? I couldn't find out how.

www.example.com/A1B2C3

instead of

www.example.com/index.html?key=A1B2C3

I'm using Google App Engine and GWT. All in Java.

This is a cool question. I figured out how to do it for python as well.

app.yaml:

- url: /test/(.*)
  script: test.py \1

test.py:

#!/usr/bin/env python

import sys

def main():           
  for arg in sys.argv:
     print arg

if __name__ == '__main__':                               
  main()
