Hi all,

Trying to get to grips to ajax... I have written a script to check the response of a php page... as of the minute the php page simply returns "0", However it seems that no matter what the content of the php page (LiveAssistanceHandle.php), the result always comes back as "1".

Can anyone point out my mistake here?

	function init(){
		var xmlhttp;
		if (window.XMLHttpRequest)
		  {// code for IE7+, Firefox, Chrome, Opera, Safari
		  xmlhttp=new XMLHttpRequest();
		  }
		else
		  {// code for IE6, IE5
		  xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
		  }


			xmlhttp.onreadystatechange=function()
			  {
			  if (xmlhttp.readyState==4 && xmlhttp.status==200)
			    {
				    var response = xmlhttp.responseText;
					if (response == "1"){
						alert ("Picked Up - " + response);
					}else{
						alert ("Not Picked Up - " + response);
					}	
			    }
			  }
		xmlhttp.open("GET","LiveAssistanceHandle.php",true);
		xmlhttp.send();			


	}


	window.onload = init;

no worries, I found the problem.... This happens every time I go to use ajax and I always forget so for anyone else that reads this with the same problem...

Once the page has been requested once, my browser seems to be cacheing it.. so if it requests the same page again, rather than contacting the server, it just uses the same response as last time.

I fixed this using this...


xmlhttp.open("GET","LiveAssistanceHandle.php?refresh=" + (new Date().getTime()),true);


Anyone happen to know why this always happens, is there a known fix around it other than the one I just posted?
