| - | If it came to a redirect loop, it means GeoIP module was actually working. How the redirect loop occurs? While for such subfolder redirect, you might need to be more careful. The reason you get a redirect error, is because the rules will be evaluated again after the redirect has been performed, so if you access ''/'' it gets redirected to e.g. ''/us'', then on ''/us'', it will be asked to redirect again to ''/us'' - and you end up with a loop. The fix is to add an additional condition to prevent this, such as ''RewriteCond %{REQUEST_URI} !^/us[NA]''. So what it does, is to only redirect to /us if country code from the GeoIP matches US and the request URI doesn't start with /us. | + | The redirect loop actually indicates the the GeoIP module is working. |
