Clicking the link above will send an Ajax request to the server which returns
a url to redirect to. The url is returned from the server in a custom response
header called 'REDIRECT_URL'.
Since Ajax does not support redirects, JavaScript is used to simulate a redirect
by setting the value of window.location to the redirect url.
