           Summary: XMLHttpRequest's abort() causes "Failed to load
                    resource: cancelled" error
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh Intel
        OS/Version: Mac OS X 10.6
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: jaka at kubje.org


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
