Con el objetivo de bloquear posibles filtraciones de datos confidenciales, por defecto, al navegar a otros sitios, el encabezado HTTP Referer incluir\u00e1 solo el dominio, no la URL completa de origen desde la que se realiza la transici\u00f3n. La ruta y los par\u00e1metros de la consulta ser\u00e1n eliminados. Es decir, en lugar de \u00abReferer: https:\/\/www.example.com\/path\/?argumentos\u00bb se transmitir\u00e1 \u00abReferer: https:\/\/www.example.com\/\u00bb. Desde Firefox 59, dicha limpieza se llevaba a cabo en modo de navegaci\u00f3n privada, y ahora se extender\u00e1 al modo principal.      <\/p>\n<p>Este nuevo comportamiento ayudar\u00e1 a prevenir la transmisi\u00f3n de datos innecesarios sobre el usuario a redes publicitarias y otros recursos externos. Como ejemplo, se mencionan algunos sitios m\u00e9dicos, donde durante la visualizaci\u00f3n de anuncios, terceros pueden obtener informaci\u00f3n confidencial, como la edad y el diagn\u00f3stico del paciente. Sin embargo, la eliminaci\u00f3n de detalles del Referer puede afectar negativamente la recolecci\u00f3n de estad\u00edsticas de tr\u00e1fico por parte de los propietarios de sitios, quienes ahora no podr\u00e1n determinar con precisi\u00f3n la direcci\u00f3n de la p\u00e1gina anterior, por ejemplo, para entender de qu\u00e9 art\u00edculo particular se realiz\u00f3 la navegaci\u00f3n. Tambi\u00e9n puede interrumpir el funcionamiento de algunos sistemas de generaci\u00f3n din\u00e1mica de contenido que analizan las claves que generaron la navegaci\u00f3n desde un motor de b\u00fasqueda.     <\/p>\n<p>Para gestionar la emisi\u00f3n del Referer, se ha previsto el encabezado HTTP Referrer-Policy, con el cual los propietarios de sitios web pueden redefinir el comportamiento por defecto para las transiciones desde su propio sitio y devolver la informaci\u00f3n completa en el Referer. Actualmente, por defecto se aplica la pol\u00edtica \u00abno-referrer-when-downgrade\u00bb, donde el Referer no se env\u00eda al cambiar de HTTPS a HTTP, pero se transmite en su forma completa al cargar recursos por HTTPS. A partir de Firefox 87, comenzar\u00e1 a regir la pol\u00edtica \u00abstrict-origin-when-cross-origin\u00bb, que implica recortar rutas y par\u00e1metros al enviar solicitudes a otros hosts al acceder por HTTPS, eliminar el Referer al cambiar de HTTPS a HTTP y transmitir el Referer completo para transiciones internas dentro de un mismo sitio.     <\/p>\n<p>El cambio se aplicar\u00e1 a solicitudes de navegaci\u00f3n normales (transiciones a trav\u00e9s de enlaces), redireccionamientos autom\u00e1ticos y al cargar recursos externos (im\u00e1genes, CSS, scripts). En Chrome, la transici\u00f3n a \u00abstrict-origin-when-cross-origin\u00bb se implement\u00f3 el verano del a\u00f1o pasado.<br \/>\n<br \/>Fuente: <a content=\"nofollow\" rel=\"nofollow\"
