41e3d6b4e67a52c6570c0412c3e5526278cf07d7nd <p>Un <em>filtro</em> es un proceso que se aplica a los datos que
41e3d6b4e67a52c6570c0412c3e5526278cf07d7nd se reciben o se env&#237;an por el servidor. Los datos enviados
41e3d6b4e67a52c6570c0412c3e5526278cf07d7nd por los clientes al servidor son procesados por <em>filtros de
41e3d6b4e67a52c6570c0412c3e5526278cf07d7nd entrada</em> mientras que los datos enviados por el servidor se
41e3d6b4e67a52c6570c0412c3e5526278cf07d7nd procesan por los <em>filtros de salida</em>. A los datos se les
41e3d6b4e67a52c6570c0412c3e5526278cf07d7nd pueden aplicar varios filtros, y el orden en que se aplica cada
41e3d6b4e67a52c6570c0412c3e5526278cf07d7nd filtro puede especificarse explícitamente.</p>

41e3d6b4e67a52c6570c0412c3e5526278cf07d7nd <p>Los filtros se usan internamente por Apache para llevar a cabo
41e3d6b4e67a52c6570c0412c3e5526278cf07d7nd funciones tales como chunking y servir peticiones de
41e3d6b4e67a52c6570c0412c3e5526278cf07d7nd byte-range. Además, los m&#243;dulos contienen filtros que se
41e3d6b4e67a52c6570c0412c3e5526278cf07d7nd pueden seleccionar usando directivas de configuraci&#243;n al
41e3d6b4e67a52c6570c0412c3e5526278cf07d7nd iniciar el servidor. El conjunto de filtros que se aplica a los
41e3d6b4e67a52c6570c0412c3e5526278cf07d7nd datos puede manipularse con las directivas <directive
