AJAX stand for Asynchronous JavaScript and XML. Contrary to what some people think, It is not a programming language, instead you can see it as a technique of using existing technologies. If you must succeed in becoming an AJAX professional; you must be very good in using/writing code in Xhtml (WYSISWYG users might find it difficult to use AJAX) you must learn how to write codes,and any server-side programming language like php. The technologies you need is a markup language like Xhtml, a scripting language like Javascript and a server-side programming language like php. Differrent professionals have various reasons of developing their websites/ web applications with AJAX, but the major aim of ajax is swift processing of data, because with ajax you can retrieve only the information you need at a particular instance from the server using the xmlhttprequest object of javascript, thus the page does not have to reload before retriving information from the server. We will talk about this next time, mean while if you have any question, ask.

Let the newbies see something like an image preloader using Ajax.

AJAX is bigger than that, Aim at building a complete e-commerce solution (shopping cart, e-payment systems like ATM, Egold, Credit card like VISA, MASTER) with AJAX, even user management systems. an <img> preloader is the simplest task you can acrry out with AJAX, think of testing if the respondsText have been completely downloaded, if not just simply use javascript's DOM to locate a gif or swf file until the responsText or Xml have been received. e.g

if (xmlhttp.readyState==4 && xmlhttp.status==200){
// set the content of the appropriate element to xmlhttpobject.respondsText
}
else
{
// set the content of the appropriate element to e.g images/animated.gif or swf (you must use the xhtml object element in this case, and ensure your properties are cross-browzer compatible
}

You may want to check up your source codes for any unfamiliar codes that may have been injected.
Also do well to check your firewall logs.
If you have root access to the server you're on, change familiar ports like SSH to a non-standard port.
Just go through any access logs you can lay hands on.
