Si no volem que una determinada p\u00e0gina web quedi mai en mem\u00f2ria cau, independentment del navegador que utilitzin els usuaris i de la seva configuraci\u00f3, n’hi han una s\u00e8rie de cap\u00e7aleres que s’han de posar al inici de les nostres p\u00e0gines.<\/p>\n

Aquestes cap\u00e7aleres son:
\nCache-Control: no-cache, no-store, must-revalidate
\nPragma: no-cache
\nExpires: 0<\/code><\/p>\n

Aix\u00ed doncs, en HTML serien:<\/p>\n

<meta http-equiv=\"Expires\" content=\"0\" \/>
\n<meta http-equiv=\"Cache-Control\" content=\"no-cache, no-store, must-revalidate\" \/>
\n<meta http-equiv=\"Pragma\" content=\"no-cache\" \/><\/code><\/p>\n

i en PHP:<\/p>\n

header('Cache-Control: no-cache, no-store, must-revalidate'); \/\/ HTTP 1.1.
\nheader('Pragma: no-cache'); \/\/ HTTP 1.0.
\nheader('Expires: 0'); \/\/ Proxies.<\/code><\/p>\n

I si es vol deshabilitar en tota la carpeta es pot fer creant un fitxer .htaccess i afegir el seg\u00fcent:<\/p>\n
