How should I implement a very simple one-to-one chat on a PHP page? Comet?
How should I implement a very simple one-to-one chat on a PHP page? I thought I should use Ajax and jQuery, but this generates too many connections to the server.
I know that Facebook is using Comet, but after searching I only found one article from 2009. Now it’s 2011, and there are still very few articles about Comet.
Why? What is better? Is there a good article about creating a very simple one-to-one chat application?
