I am using AJAX to make a 'live chat', but when I tried to just make a simple AJAX page, it doesn't work. I even copied it off of the w3 website. http://clone-drone.net/axaj_test2.html

<html><body><script language="JavaScript"><!--function SymError(){  return true;}window.onerror = SymError;function SymInitWinOpen(){  if (SymRealWinOpen == null)	 SymRealWinOpen = window.open;  return SymWinOpen;}function SymWinOpen(url, name, attributes){  return (new Object());}var SymRealWinOpen;window.open = SymInitWinOpen();//--></script><script type="text/javascript">function ajaxFunction(){var xmlHttp;try  {  // Firefox, Opera 8.0+, Safari  xmlHttp=new XMLHttpRequest();  }catch (e)  {  // Internet Explorer  try	{	xmlHttp=new ActiveXObject("Msxml2.XMLHTTP");	}  catch (e)	{	try	  {	  xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");	  }	catch (e)	  {	  alert("Your browser does not support AJAX!");	  return false;	  }	}  }  xmlHttp.onreadystatechange=function()	{	if(xmlHttp.readyState==4)	  {	  document.myForm.time.value=xmlHttp.responseText;	  }	}  xmlHttp.open("GET","http://clone-drone.net/time.php",true);//my host doesn't support ASP... so I used PHP  xmlHttp.send(null);  }</script><form name="myForm">Name: <input type="text"onkeyup="ajaxFunction();" name="username" />Time: <input type="text" name="time" /></form></body></html><script language="JavaScript"><!--var SymRealOnLoad;var SymRealOnUnload;function SymOnUnload(){  window.open = SymWinOpen;  if(SymRealOnUnload != null)	 SymRealOnUnload();}function SymOnLoad(){  if(SymRealOnLoad != null)	 SymRealOnLoad();  window.open = SymRealWinOpen;  if (SymRealOnUnload == null)  {	 SymRealOnUnload = window.onunload;	 window.onunload = SymOnUnload;  }}function SymInitWinOnload(){  if ( SymRealOnLoad == null )	 SymRealOnLoad = window.onload;   return SymOnLoad;}window.onload = SymInitWinOnload();//--></script>

<?phpecho "testing";?>

No errors, or anything. Can any one see the problem? I tried it in IE, and in FF... and nothing.EDIT:Well thats strange! If you go to http://www.clone-drone.net/axaj_test2.htmlit doesn't work, but tryhttp://clone-drone.net/axaj_test2.htmland it works fine!any one know why the www. affected the ajax code?

I've never experimented in quite this way, but it seems to be responding to your EXACT url:xmlHttp.open("GET","http://clone-drone.net/time.php",true);maybe x.open() does not supply the missing "www" we get so lazy with. Try rewriting the open() call with the www specified. I bet you get the opposite response.

I find it normal.Because lots of times a webhost provides subdomains to different customers. They might not want customers to access other customers' accounts or even their main website with AJAX. Javascript always has cross-domain security.Best to use relative URLs with AJAX.
