//Generic AJAX object for all types of HTTP get/post work //
//Author: Debabrata Kar (dk.webtenet@gmail.com) //
//Usage: //
// var ajax = new AJAX(); //
// var arrParam = new Array(); //
// arrParam['name1'] = 'value1'; //
// arrParam['name2'] = 'value2'; //
// arrParam['name3'] = 'value3'; //
// ajax.getRequest(url, arrParam, responseHandler); //
// OR //
// ajax.postRequest(url, arrParam, responseHandler); //
// //
// NOTE: You do not need to escape() or encodeURIComponent() the //
// parameter names or values. AJAX will do it on its own. //
// You need to define responseHandler() function that will handle //
// response back from the server, be it XML or anything else //
