solo acepta url de mi dominio

[aplicacion1992]

Hola amigos del foro, pues hoy os vengo a molestar de nuevo, pasa que descargue un codigo php para emular un proxy transparente y cuando pongo mi dominio "mjrosse.info" en la configuracion proxy y despues inserto una direccion me da este error "Error: Only HTTP request are supported !" pero cuando pongo por ejemplo mjrosse.info/ladireccion me funciona significa que algo en el codigo solo me esta permitiendo acceso sobre el mismo dominio Porfavor me podrian ayudar que ya llevo dias sin encontrar que es el problema

Código HTML:

                $headers[str_replace(' ', '-', ucwords(str_replace('_', ' ', strtolower(substr($key, 5)))))] = $value;
            }
