清除网页缓存(html asp php java)

清除缓存我们只需要设置页面为no-cache就可以了,当然像asp,php这种只需要设置Expires操作即可,具体如下.

HTML网页:

ASP网页:

Response.Expires = -1 
Response.ExpiresAbsolute = Now() - 1 
Response.cachecontrol = "no-cache"

PHP网页:

header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); 
header("Cache-Control: no-cache, must-revalidate"); 
header("Pragma: no-cache");

JSP网页

response.setHeader("Pragma", "No-cache"); 
response.setHeader("Cache-Control", "no-cache"); 
response.setDateHeader("Expires", 1);
