有时候我们不希望浏览器使用缓存加快网页的显示,尤其是那些论坛之类的频繁更新内容的网页,在网上有说可以使用下面的方法来屏蔽缓存,但是我试了效果不好。
某日我突发奇想,找到了一种在任何情况下都会显示最新的网页内容的方法,描述如下:
请将网页的链接改为:
http://xxx.yyy.zzz/page.php?rand=XXXXXXX
其中http://xxx.yyy.zzz/page.php是你的网页,rand是一个你不会用到的Qurey字串,XXXXXXX是一个随机字串。
也就是说,只要在链接的Url加入了一个不会影响网页的内容的随机字串,从而使得每次访问该网页的Url都不同,从而可以使浏览器不使用缓存中已有的该网页,而使每次显示的都是最新的内容。
