python webserver question

[dale bryan]

I am working on a task to display a wireless network nodes using Google Earth (GE) with KML network links.  I am using a simple python webserver (see code below) to serve up the python scripts as KML output to GE for this.

import BaseHTTPServer
import CGIHTTPServer
class Handler(CGIHTTPServer.CGIHTTPRequestHandler):
    cgi_directories = ['/cgi-bin']              
httpd = BaseHTTPServer.HTTPServer(('',8000), Handler)
httpd.serve_forever()

This works fine for my initial scripts, but now I thinking of combining the python scripts into the server program and making things more efficient.  The script file currently reads sensor data from different I/O ports (GPS ->serial, network data -> ethernet).  I am new to python, and was wondering if there might be a better way to run the server side process than how I am doing it now:

1. GE client requests data through KML network link on a periodic update interval
2. python webserver handles request and executes python script in cgi-bin directory
3. python script reads sensor input from serial and ethernet ports and writes data as KML output to GE client
4. repeat process at update interval

I am thinking if it would be better to make the process server-side focussed as opposed to client side.  Have the server only update sensor data to the client when there has been a change in sensor data, and only send the data that has changed.  Has anyone had experience in doing this with python that could point me in the right direction?

thx
Dale
