This document discusses techniques for real-time web applications, including Comet, polling, long polling, and streaming. It reviews browser techniques like XHR, iframes, and websockets. Server-side options are examined, with criteria like performance, supported techniques, and programming languages. Several specific server implementations are highlighted, including Orbited, APE, and Lightstreamer. A comparison table of capabilities for different servers is proposed. The presentation concludes with contact information for the speaker.
