On-board vs. Off-board Comet. Useful distinction. On-board comet runs on the same server as the rest of your application; Off-board comet is served from a separate server (generally a subdomain) and a separate stack. If you want to stick with PHP, Rails or Django for the rest of your site off-board comet looks like the way to go. # 22nd May 2008, 5:02 pm
