Real time server
- 1. Real-time Webserving Playing around with Tornado Web Server
- 2. Lean Basics While Tornado is similar to existing Web-frameworks in Python (Django, Google's webapp, web.py ), it focuses on speed and handling large amounts of simultaneous traffic.
- 3. RSS reader flagged/read/favourite/selected Show current status/price for a number of products Ask the server to process an image Routing chat between webapps Web User Scenarios
