Prototyping: Simplest HTTP server with URL routing (to use w/ Backbone.Router)?

We're working on a Backbone.js application and the fact that we can start a HTTP server by typing python -m SimpleHTTPServer is brilliant.

We'd like the ability to route any URL (e.g. localhost:8000/path/to/something) to our index.html so that we can test Backbone.Router with HTML5 pushState.

What is the most painless way to accomplish that? (For the purpose of quick prototyping)

Just use the built in python functionality in BaseHTTPServer

import BaseHTTPServer

class Handler( BaseHTTPServer.BaseHTTPRequestHandler ):
    def do_GET( self ):
        self.send_response(200)
        self.send_header( 'Content-type', 'text/html' )
        self.end_headers()
        self.wfile.write( open('index.html').read() )

httpd = BaseHTTPServer.HTTPServer( ('127.0.0.1', 8000), Handler )
httpd.serve_forever()
