Description Jaka Jančar 2010-08-06 01:58:55 PDT 
My webapp may abort XMLHttpRequests, if the data is no longer needed, before it has finished loading. This is normal behavior.

Unfortunately, this causes a bunch of "Failed to load resource: cancelled" errors in the console.

Setting an onabort handler doesn't make a difference. Wrapping abort() into try..catch doesn't either.

Example:

var xhr = new XMLHttpRequest;
xhr.open('GET', 'http://www.google.com/');
xhr.send();
xhr.abort(); // www.google.com Failed to load resource: cancelled

Yes, we probably shouldn't be logging the cancelled error.
