Ajax and status 302

I'm having a problem with ajax (and/or jQuery ajax) and status 302.

This is what I am trying:

var xhr = new XMLHttpRequest();
xhr.open("GET", 'some_page_that_I_cant_change.php');
xhr.onreadystatechange = function(){
    console.log(xhr.readyState, xhr.status);
};
xhr.send(null);

The some_page_that_I_cant_change.php redirects to a .bin with 302 code. I do not want to download this file, I just want know the path to the file. Example:

./some_page_that_I_cant_change.php
./path/to/bin/file.bin << I wan't only this path as string

The problem is that Chrome automatically redirects to the file, without telling me the path to script. Is there a workaround for this?

In a word: I don't think you can do that cause of HTTP protocol.
HTTP protocol([1]:http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html) stipulate 302 means redirect URI, and browsers follows.So,the javascript can't get the redirect response, just get final response.

So,You have to get path by response body.

If you use a HEAD request instead of a GET request, I suspect that will do what you want. You should only see headers in the response, no response body (i.e., no .bin will download).
