Ajax Help httpRequest

[matt88e]

Ok i do PHP, Java, SQL & a little bit of here & there stuff


Ajax httpRequest just confuses me on how to use it period.
I would like help. I would like help on making a script

Simple http Request to do a check on the current page constantly.

This script i plan to put into a Live Chat Room.

Another side question on the same subject. I'll be using php/SQL mysql_fetch_array & ORDER/LIMIT in the chat. Not sure, but at least i want the first question answered, getting the more complicated if it is dont later.

http://w3schools.com/ajax/default.asp is the site where I learned how to use AJAX.
If you want, I could PM you one of my codes that I use for my site (http://saumpro.com/user.php?t=reg is done with AJAX, the name check and registration)
