the iframe is the transport channel that is carrying the form posting, so Atanas is correct, you have to stop the transport inside the iframe.

here is a way of doing it depending on browser:

if (iframeObj.contentWindow.document.execCommand)
    { // IE browsers
        iframeObj.contentWindow.document.execCommand('Stop');
    }
else
    { // other browsers
        iframeObj.contentWindow.stop();
    }
// notify user upload was cancelled, remove spinner images, etc

Try this:

iframe.contentWindow.stop(); //for anything but IE
iframe.contentWindow.document.execCommand("Stop"); // for IE

Currenty setting iframe src to "javascript:false" works for me.

I'm not sure but i guess removing the iframe from the dom should be enough?
