Yeah, I had a dog named Ajax. Of course, we named her after the cleaning powder, not the mythological figure.

Okay, so ajax is a term first introduced in this blog entry:

QUOTE(http://www.adaptivepath.com/publications/essays/archives/000385.php)

The name is shorthand for Asynchronous JavaScript + XML, and it represents a fundamental shift in what’s possible on the Web.
Defining Ajax

Ajax isn’t a technology. It’s really several technologies, each flourishing in its own right, coming together in powerful new ways. Ajax incorporates:

    * standards-based presentation using XHTML and CSS;
    * dynamic display and interaction using the Document Object Model;
    * data interchange and manipulation using XML and XSLT;
    * asynchronous data retrieval using XMLHttpRequest;
    * and JavaScript binding everything together.

Essentially, it is the fusion of several existing technologies that allow websites to be ultra-responsive. Have you gotten a gmail account recently? When you fill in your password that you want, the form automatically checks the strength of the password and reports back to you within a few seconds, and the cool thing is you don't have to click anything. The page is using ajax to update itself according to your input to form elements even before you hit the submit button.

The article has some cool diagrams and a more detailed explanation.

AJAX is not really that hard to learn, if you know a good amount of javascript, that is. I am not an expert in javascript, but all I had to do was figure out the XML connection properties of certain browsers, then you can import text or XML into javascript (which is running after the page loads) and print it to a specifyed <div> tag. I might need a little help, but I might be able to come up with a tutorial.

As to how I have been using AJAX, only for content loading without reloading the whole page, just the content. Nothing fancy like Google Maps...

MICROSOFT:  I'm pretty sure runescape uses a java applet, not AJAX.

runescape definitely uses a java applet, which actually works more like a full flash website...AJAX is essentially XHTML and JavaScript brought together to create a very nice, generally quick web application that does not require the end-viewer to reload the general page. You might say that AJAX is similar to iframes (or just frames in general) that confine to the latest web standards...

It helps in reducing bandwidth usage - only small XML bits are sent to and from the server. Fast? You bet! Gmail is 20x faster than Hotmail.

Yes, because is so much depended on client machine......

Very true, but that is also what makes it so powerful, especially since the page that features AJAX does not have to be reloaded--it just sends a "background request" for the new content!

Simple in concept, yet complex in application...

I recently came to know that Gmail works on AJAX and that is the reason behind the quick response to user actions, whether it is opening a mail or composing or email address auto complete.

First of all, thanks for the link (although it is just the simple, wonderful Wikipedia). Anyway, Google seems to be leading the charge with large-scale AJAX implementations. Not only is Gmail designed using AJAX, but Google Maps and Google Suggest are also top-notch AJAX applications.

1. Ajax: Achieve Ajax Program In 5 Lines Of Code! - (1)

   Well Last night, after a week of irritation and errors I finally created an easy Javascript object
   that easily and quickly allows you to develop an AJAX program in just 5 easy steps! Here's
   the link to the object I've created: http://www.demolaynyc.astahost.com/ajaxConn/ajaxConn.js
   Download it and read the Readme file that's under the same directory:
   http://www.demolaynyc.astahost.com/ajaxConn/Readme.html Basically what this object does is to
   connect to a server-side script (".php, .asp, .jsp, etc"), and what ever this script displays is

4. Concerns On Ajax With Java - (3)

   Source article from Sun: http://java.sun.com/developer/technicalArticles/J2EE/AJAX/ Well, from
   this article, it shows that Ajax can be achieved with Java using Java Servlets or JSP's. For
   those who don't know what AJAX is, it's an object in Javascript technology that allows for
   instant communication between client-side and server-side. It's like changing a page's
   content without having to reload the whole page. Let's move on... Now when I looked at the JSP
   source code, the servlet's function was to simply validate a text and send back a r...

5. Remote Ajax - Wtf?! (1)

   Any reason why Ajax doesn't work remotely? It looks almost as if ajax only works if its getting
   or sending info from the same server. What gives? could this have anything to do with the possible
   abuse of brute force scripts? If so, wouldn't this be a limitation in the browser only? Are
   there any browsers that allow remote Ajax? ...or am I doing something wrong? (I left that question
   at the end for a reason... I am sure that my script is flawless seeing as it works perfectly if i
   try to access something locally, but the second I try something remote, no info ...

7. Help With Ajax - I can't figure it out... (0)

   Hello, I have recentlty ran into a problem on my website : When a user logs in, it adds him to an
   active users list in the MySQL database, but if they don't click the "logout" button, and just
   leave the site, it keeps them in the active users list forever until I manually go into the database
   and take them out. I heard from a friend that you could use AJAX to find out if the user is active,
   if he's not and he stays inactive for a certain amount of time, then it will take him out of the
   active users list. So I go to learn AJAX because all of the other languages I...
