This “layer 8” form of error correction just isn’t possible in an Ajax-style Web application where network activity may be happening at any moment.

Onerror = function(){cancelRequest(target, "Server error",current Request,timer);}; It is also important to address the possibility that the response image is not generated in a timely manner. To mitigate such a problem we can set a timeout value, and if the timer fires before receiving the image, alert the user. /* function to cancel request if network timeout occurs */ networkTimeout = function(){cancelRequest(target, "Network timeout",currentRequest);}; /* define network timeout in milliseconds and bind to timeout function */ var timer = setTimeout("networkTimeout()",timeout*1000); When employing this technique, it is important to clear any timeouts that may be running if data is received successfully.
