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。
