Preguntas frecuentes
¿Esto lista cada código de estado posible?
Cubre los códigos usados comúnmente que encontrarás en el desarrollo web cotidiano, no cada código jamás registrado.
¿Puedo buscar por una descripción parcial?
Sí — buscar "timeout" o "redirect", por ejemplo, encuentra cada código de estado coincidente.
¿Se incluyen códigos personalizados o no estándar?
No — aquí solo se listan los códigos registrados formalmente en IANA, no los códigos específicos de aplicación o no estándar que usan algunas APIs.
