In the case above you're monitoring only a redirect, which doesn't
really means much. you can use the --onredirect switch (see check_http
- --help) to follow redirects.

Even when following redirects, it calculates only the time taken to load
the main page, no resources (css, js, images, iframes) will be loaded.

If you need something more complete you should have a look at WebInject,
although I have no personal experience with it.

Even WebInject does not run JavaScript... I'm not aware of any free
solution that does it right now, so results may be very different from
reality on pages that rely a lot on them (Ajax, "Web 2.0"...)
