Rails spinoffs - Feb 2006 - Ajax reqest and http status

Hi all. I ''m using Ajax request on my site and i need to show some
message wneh AJAX call is running, (sometimes it happen so slow). I find that
object AJAX.RESPOND is very usefull here, but sometimes when i need to do AJAX
CALL my ajax call is redirect and i want to when it happen, is there way to find
status of ajax call? i don''t know where I can find this property in
AJAX.Request, Ajax.Responder or maybe it doesn''t exist?  I know that
using clear xmlhttprequest there is a property called
request.status. And one thing more - i hear that IE is caching AJAX call. That
mean if something is changed on serverside browser still use data from cache. Is
there a way to avoid this? i hear that other ajax library use uniqueParameter to
force browser not caching ajax call.
Best wishes 
Gregor

You should be able to do something like this:

function _updateFileInfo(id,i) {	
	var rand  = parseInt(Math.random()*99999999); // chache buster
	var url   = ''./scripts/getInfo.php'';
	var param = ''id='' + id +
				''&i='' + i;
	var ajax = new Ajax.Updater(''fm-infoContent'', url, {
		method:''post'',
		//evalScripts: true,
		parameters:param,
		asynchronous:true,
		onLoading:function(request)	{
			Element.show(''fm-loading'')},

		onComplete:function(request) {
			Element.hide(''fm-loading'');			
			//updateValues();
		},		
		onFailure:_reportError
		}
	)
}

The callback functions (onComplete, onSuccess, onFailure, onXXX, etc)
all pass the transport (XMLHttpRequest) into the function as the first
parameter.  You can do transport.status to get the value you want.
