Que son las Directivas de Apache 🥇 Foro Hosting y Alojamientos Web 🗺️

Una directiva de configuración de Apache es un parámetro de configuración del Servidor Web.

Las directivas las podemos escribir de tres formas:

Directamente en el fichero de configuración para que tengan efecto en todo el servidor.

[list]En un módulo o sección de configuración, afectando también a todo el servidor.[/list]

En un fichero .htaccess, afectando solo a ese directorio y a los subdirectorios dependientes de él.

Un ejemplo de directiva es la siguiente:

ExpiresActive On

Este parámetro "ExpiresActive" lo que dice es que activa el modulo de Expires, que afecta a las funciones de cabeceras de expiración de os ficheros enviados desde el servidor web hacia los usuarios (headers) y el comportamiento de las caches que estan ecibiendo esos ficheros.
