He cogido un código de internet para cachear una pagina en php, es un cache simple. Funciona bien, si cacheo por ejemplo echo "hola"; hace el fichero de cache, etc, todo va de maravilla.
include 'cache.php';
$cache1 = new m2Cache();
$cache1->enable();
$cache1->startCache();
aquí pongo lo que quiero cachear y funciona bien.
$cache1->endCache();
Ahora.... el problema viene cuando pongo el script que quiero cachear..... es un script para mostrar rss en la web, funciona tambien bien, pero cuando lo coloco ahi en el medio no me cachea nada.... aunque sigue funcionando bien el script de rss.
Pego aquí el script que pego ahi en el medio y no funciona:
