XMLHttpRequest follows the redirect automatically by default so you don't see the 302 response. You need to set nsIHttpChannel.redirectionLimit property to zero to prevent it:

req.open("GET","http://www.megaupload.com/?d=6CKP1MVJ",true);
req.channel.QueryInterface(Components.interfaces.nsIHttpChannel).redirectionLimit = 0;
req.send(null);

Not that the link you use here redirects anywhere but this is the general approach. Btw, instead of looking at the response text for redirects you should look at req.getResponseHeader("Location").
