function ShowFolderFileList() {


var xmlHttp;

var lstArray = new Array();

//Let us create the XML http object
xmlHttp = null;

if (window.XMLHttpRequest) {
//for new browsers
xmlHttp = new XMLHttpRequest();
}
else if (window.ActiveXObject) {
//for old ones
xmlHttp = new ActiveXObject("Microsoft.XMLHTTP");
}

if (xmlHttp != null) {

//Handle the response of this async request we just made(subscribe to callback)
xmlHttp.onreadystatechange = function () {

if (xmlHttp.readyState == 4) {
//loaded

if (xmlHttp.status == 200) {
//request was successful. so Retrieve the values in the response.
var pages = xmlHttp.responseText.split(';');
var dataCount = pages.length;
for (var i = 0; i < dataCount; ++i) {
lstArray[i] = '[' + pages[i] + ']';
}
//return loadCKEditorPlugin(lstArray);

}
}
}

//Pass the value to a web page on server as query string using XMLHttpObject.
xmlHttp.open("GET", "/ckeditor/plugins/simpleLink/pages.aspx", true);
xmlHttp.send(null);
}
