| 以下是引用片段: Response.Buffer = True Response.ExpiresAbsolute = Now() - 1 Response.Expires = 0 Response.CacheControl = "no-cache" Response.AddHeader "Pragma", "No-Cache" |
| 以下是引用片段: <HEAD> <META HTTP-EQUIV="Pragma" CONTENT="no-cache"> <META HTTP-EQUIV="Cache-Control" CONTENT="no-cache"> <META HTTP-EQUIV="Expires" CONTENT="0"> </HEAD> |
前两个方法据说有时会失效,而第三种则是在跳转时传一个随机的参数! 因为aspx的缓存是与参数相关的,假如参数不同就不会使用缓存,而会重新生成页面,每次都传一个随机的参数就可以避免使用缓存。这个仅适用于asp&asp.net
4、在jsp页面中可使用如下代码实现无缓存:
| 以下是引用片段: response.setHeader("Cache-Control","no-cache"); //HTTP 1.1 response.setHeader("Pragma","no-cache"); //HTTP 1.0 response.setDateHeader ("Expires", 0); //prevents caching at the proxy server |
这些代码加在<head> </head>中间具体如下
| 以下是引用片段: <head> <% response.setHeader("Cache-Control","no-cache"); //HTTP 1.1 response.setHeader("Pragma","no-cache"); //HTTP 1.0 response.setDateHeader ("Expires", 0); //prevents caching at the proxy server %> </head> |
