推荐答案

您应该设置正确的HTML头。据<一个href=\"http://stackoverflow.com/questions/49547/making-sure-a-web-page-is-not-cached-across-all-browsers\">this这些都是在所有浏览器工作的：

You should set the correct HTML headers. According to this these are the ones that work on all browsers:

Cache-Control: no-cache, no-store, must-revalidate
Pragma: no-cache
Expires: 0

您可以将它们像这样：

HttpContext.Current.Response.AddHeader("Cache-Control", "no-cache, no-store, must-revalidate");
HttpContext.Current.Response.AddHeader("Pragma", "no-cache");
HttpContext.Current.Response.AddHeader("Expires", "0");
