Mootools: How to get redirected if ajax request returns redirect code?

问题

I need to redirect user if request returns 302 or 303. It seems that there isn't a standard way to do this (odd, I thought it's quite a common task).

I have this code:

var request = new Request({
        url: "/some-url/",
        method: 'get',
        evalScripts: true,
        onComplete: function(){
            console.log(this.status);
        }
    });

Console prints 0 status but web inspector shows that the status code is 302 Found, so I can't manually check the code and get redirected. Anyone know what I'm doing wrong?

Thanks.

回答1:

normally, an ajax request to a 301/302/303 etc will follow the new location and re-issue the request as per specification. if you are not seeing a second request, something is wrong, like an infinite loop or similar...

回答2:

I've tryed both cases (302 and 303) and it follows the spec: user agent automatically redirects to url, specified in the Location: header of response. So, finally console.log(this.status) indeed return 200, but no worry because redirect is handled by browser automatically (at least in FF and Chrome).

That is the firebug console:
