推荐答案

这意味着不缓存 ...没有浏览器历史记录. .

Expires属性以分钟为单位指定在浏览器上缓存的响应页面到期之前的时间长度.

因此，将这段时间设置为零，则每次访问该页面时都将刷新(重新加载)该页面，而不是将其存储在缓存中.

This means no caching... no browser history...

The Expires property specifies a length of time in minutes before a response page cached on the browser expires.

Thus giving this time as ZERO, the page is to be refreshed (reloaded) every time it is accessed, rather than being stored in a cache.
