IE Bug with 204 HTTP responses - workaround in mootools

Reported by Juri Kuehn | April 7th, 2009 @ 11:50 AM | in 2.0 (closed)

Internet Explorer (including the brand new shiny IE8 ....) got a bug, where 204 http responses are sometimes transformed to 1223.

This leads to the triggering of onFailure event instead of onSuccess when using the Mootools Request object.

YUI and jQuery implemented a workaround for this bug. Can this also be implemented in mootools?

    mmm maybe you can change the isSuccess function of the Request Object:

    @@@javascript isSuccess: function(){

    return ((this.status >= 200) && (this.status < 300));


    in this way:
    isSuccess: function(){
    	return ((this.status >= 200) && (this.status < 300)) || (Browser.Engine.trident && this.status == 1223);

    • State changed from “new” to “open”
    • Assigned user set to “Valerio”

    The correct way to implement your own isSuccess is by either .implement-ing it into the Request class or just pass it as an option.

    A fix is in the works, in the meantime you can just implement a custom isSuccess with the correct checks to this.status.

    Great, thank you very much. The suggested snippet by Daniele is working correctly and is a good solution until next release.

    What works better for us is to change in class Request:


    isSuccess: function(){

    return (((this.status >= 200) && (this.status < 300)));



    isSuccess: function(){

    if (this.status == 1223) this.status = 204; // ie fix, see
    return (((this.status >= 200) && (this.status < 300)));


    ie accepts the change of the status. this way you dont need to intercept status 1223 in your code and can continue working with 204
