網頁的緩存是由 HTTP消息頭中的“Cache-control”來控制的，常見的取值有private、no-cache、-age、must-1-cache、must---control: -age=52---3-revalidate、--4-control值為“no-: Fri, 31 Dec 1999 16:00:00= no-=no-= -1-1.1服務器指定 CacheControl = no-1.0 服務器不能使用 Cache-1.0 服務器，IE使用Pragma:no-:
則 Internet Explorer不會緩存此響應。注意：Pragma:no-cache 僅當在安全連接中使用時才防止緩存，如果在非安全頁中使用，處理方式與 Expires:---
