AJAX - settimeout problem?

[sayedsohail]

hi everyone,  this is related to ajax question:  I am trying to reset the xmlhttp in the nested loop:  i.e, if the satus is not 200 than it should abort and try again for couple of times before it gave up, than it should display a message to the user.  rather than just showing alerting the user.

 

var iInterval=1000;
function handleEventsites() {

// check the readystate == 4

if(httpsites.readyState == 4) 
	{
	 // continue only if HTTP status is "OK"
		if(httpsites.status == 200)
		{
			// read the response
			var response = httpsites.responseText;
			// server error?
				if (response.indexOf("ERRNO") >= 0 
				|| response.indexOf("error") >= 0
				|| response.length == 0)
				setTimeout(handleEventSites,iInterval);
				//alert(response.length == 0 ? "Server error." : response);
				// if everything went well, display datagrid
				else 

				document.getElementById("displaysites").innerHTML = response;


		}
		else 
		{    

			// undo any changes in case of error
			setTimeout(handleEventSites,iInterval);
			//alert("Error on server side.");

    
		}
		}
else {
// checking the httpsites readystate and display appropriate message if it fails otherwise just update the div
	document.getElementById('displaysites').innerHTML = "Loading... <img src='http://localhost/images/indicator_white.gif'>";
	setTimeout(handleEventSites,iInterval);

	}					
}

The code i managed does throtlling, Is there anyway to avoid server throtlling, and abort the requests if the server is busy.

 

IF someone types quick, this is the error i am getting:

 

Error: [Exception... "Component returned failure code: 0x80040111 (NS_ERROR_NOT_AVAILABLE) [nsIXMLHttpRequest.status]"  nsresult: "0x80040111 (NS_ERROR_NOT_AVAILABLE)"  location: "JS frame :: http://127.0.0.1/dels.js :: handleEvent :: line 60"  data: no]

Thanks
