//3) AsyncReq.basedomain //The root domain executing this ajax script, taking into account the possible "www" prefix.
//4) AsyncReq.addrandomnumber //Set to 0 or 1. When set to 1, a random number will be added to the end of the query string of GET requests to bust file caching of the external file in IE. See docs for more info.

/////1) GET Example- alert contents of any file (regular text or xml file):

AsyncReq.getAjaxRequest("example.php", "name=George&age=27", processGetPost, "txt",container)

AsyncReq.getAjaxRequest(AsyncReq.basedomain+"/mydir/mylist.txt", "", processGetPost, "txt",container)

/////2) Post Example- Post some data to a PHP script for processing, then alert posted data:

//Define function to construct the desired parameters and their values to post via Ajax
function getPostParameters(){
var namevalue=document.getElementById("namediv").innerHTML //get name value from a DIV
var agevalue=document.getElementById("myform").agefield.value //get age value from a form field
var poststr = "name=" + encodeURI(namevalue) + "&age=" + encodeURI(agevalue)
return poststr
}

var poststr=getPostParameters()
