One thing I see popping up over message boards is people want to reuse the XMLHttpRequest Object instead of creating a new instance every single time. Some developers think this will help in memory leaks. I have not tested it in any way to see if it really helps. But I thought that I would show you it is possible to reuse the same object over again and again with Internet Explorer.
For this code I am going to be using a very basic example. I am not going to use OO code so just bear with it. With Firefox you are able to reuse the XMLHttpRequest object without this craziness, but with Internet Explorer 6 you are not able to do that (I have not tested this in IE 7 yet so hopefully someone will comment on the reuse factor!)
