I have a social networking site. I would like to add an exact copy of the Facebook chat. I don't know if ther's is AJAX, but our platform is built with LAMP.
* All replies that just show your (or your company's) resume will be ignored.
* An obvious merit is if you have something similar.
It is extremely important that the application or script works as fast as it does on Facebook.? I can't have a chat that updates status with long delays so that people are offline.
* Ease of use? shall be exactly the same.
* online/offline status will be retrieved from a table in the existing database.
* the response on the other user's web page must be within a few seconds.
