It is doing exactly what you asked. Use used the header() function to
redirect to a different page. The browser requested the new page and
displayed its url. If you redirect, that's how it works.
And even if the browser didn't display the URL your files would not be
secure. Security by obfustication is worse than no security - at least
with no security, you know you're insecure.
If you want to protect them from being downloaded, you need to either
use HTTP authentication or deliver the files in your script (with the
appropriate headers).
