Redirect before page load

Yes this is possible, you need to adapt this example to your needs:

Hi there, this is what we are already using but what happen is the site get to load first then redirects to the correct site. We need something that the geoip scripts will be on the header so it loads first before anything else then the redirect script. Thanks!

You can use ‘init’ or ‘plugins_loaded’ instead of the ‘template_redirect’ filter to let this be run earlier – however, not all templating function such as is_home() might work correctly by that point (the main query is initialized later I think).
