This pages sends no Location header. To be sure of this, know that this header is always accompanied with a HTTP redirection code (3xx). Here you have a code 200.

With a JavaScript-disabled browser I haven’t been redirected. This strongly hints at a JavaScript redirection. Unfortunately there is no simple way to detect that, as the page’s JS code is minified, and would require heavy work for a PHP script to analyze it.
