Get JS script source when loading from 307 redirected source

Question

Case is that:

My script inserts <script> in <head>, pointing to src1.
The back-end does 307 redirect from src1 to src2.
Script then loads src2.

But when I use this code, I'm getting src1.

var s = document.createElement("SCRIPT"), 
    h = document.getElementsByTagName("HEAD")[0]; 
    s.charset = "UTF-8";
    s.src = url;
    s.async = true;
    s.type = "text/javascript";     
    h.appendChild(s);
    s.onload = function() {
      console.log(this.src)
    }

How can I get the src2?

You might want to check if the redirect is still in effect. If you happened to test this and then switched on redirection, your browser might be using a cached version of the resource. — Joseph, Jul 16 '15 at 12:44

this.src is the src url you have set on your script tag, what you get back is the source from the temporarily redirected (307) script.

If you visit the src1 url and copy the redirect url from the response using fiddler or dev tools on your browser, you can set the that url directly in your code.

The redirecting url would be dynamicly-changed (in case of some parameters, like this: src2&param=1, src2&param=2, src2&param=3 and so on. – Maksim Slepov Jul 16 '15 at 13:00
yes, actually its not possible to get the redirect location within an XHR object, its handled earlier. I removed it form answer after reading up. – BhavO Jul 16 '15 at 13:01
why do you need the redirect url? – BhavO Jul 16 '15 at 13:02
O, it's a question for my archtector :) – Maksim Slepov Jul 16 '15 at 13:06
Query string parameters are retained when redirected, so if add the parameters to the old URL they will be carried forward to the redirected url – BhavO Jul 16 '15 at 17:22
