import BaseHTTPServer

class Serv (BaseHTTPServer.BaseHTTPRequestHandler):
    def do_GET (self):
        path = self.path.strip('/').split('/')
        self.send_response (200)
        self.send_header ('Content-type', 'text/html')
        self.end_headers()
        self.wfile.write (self.dict[path[-1]])

# load dictionary
D={'foo':1, 'bar':2}
server = BaseHTTPServer.HTTPServer (('', 8080), Serv)
server.RequestHandlerClass.dict = D
server.serve_forever()

Possibly not the best way but it should do unless someone less lazy than I
responds.  (Assuming I'm understanding your request correctly).
