How to redirect to another url using : owa_util.redirect_url?

I have an Apex 21.1.3 Page.

In the page I have a Before-Header Process with the code :

owa_util.redirect_url('https://www.google.com');
apex_application.stop_apex_engine;

When I run the page, it doesn't redirect, it shows instead the text : Location: https://www.google.com

I have the exact same code in an 19.2 Apex Application and it works correctly.

How can I solve that?

Use this instead:

apex_util.redirect_url (p_url => 'http://www.google.com/');

I mean, only this; you don't have to stop the engine, REDIRECT_URL will do it itself.
