Construyendo mi nueva web me ha surgido la siguiente necesidad. Me gustaría redirigir a todos mis visitantes según el idioma de su navegador, por ejemplo a los ingleses a la versión inglesa de mi web. La página principal está en español, a esos no quiero redirigirlos, quiero que sigan en la web normalmente.
Con el código que uso cubro esa necesidad pero no termina de funcionar correctamente, por ejemplo, a los españoles no los redirige, que es lo que quiero, pero aparece la palabra NULL en un rincón de la web, y no creo que esté bien que aparezca eso. Con los ingleses aparentemente no tengo problemas, a ellos los redirige tal y como quiero. Por lo tanto aparentemente el único problema que tengo es en mantener a los españoles en el sitio, sin ser redirigidos.
Este es el código que uso:
