When reloading a page, the onreadystatechange event fires #89
Description
This seems to cause the last message to resend.
I've noticed it with chattrr (github.com/wbecker/chattrr - hosted at chattrr.net). If you bring it up then refresh you will notice that the last message that you sent reappears.
I've trapped this by putting a window.onbeforeunload function in that sets a return value, putting a break point in and following it through, eg:
window.onbeforeunload = function (e) {
e.returnValue="stop";
return "stop";
}
It seems to go to the onreadystate handler:
XHRMultipart.prototype._get = function(){
var self = this;
this._xhr = this._request('', 'GET', true);
this._xhr.onreadystatechange = function(){
if (self._xhr.readyState == 4) self._onData(self._xhr.responseText);
};
this._xhr.send(null);
};
