Preparing the XMLHttpRequest Object
In the first step the application prepared an XMLHttpRequest object to use it for loading remote RSS data. I tested the code with firefox only, but I added ActiveXObject in case IE was used.
var RSSRequestObject = false; // XMLHttpRequest Object
if (window.XMLHttpRequest) // try to create XMLHttpRequest
RSSRequestObject = new XMLHttpRequest();
if (window.ActiveXObject) // if ActiveXObject use the Microsoft.XMLHTTP
RSSRequestObject = new ActiveXObject("Microsoft.XMLHTTP");
Writing the HTML code
Just few lines are enough, two divs are used by the application the status will inform about the progress of requesting data, and the ajaxreader will be the container in which the result will be displayed. The first thing then to do onload page is to run the AJAX Reader.

var
Backend = 'rss.php'; // Backend url .....
