什么是处理高速缓存和浏览器后退按钮的最好方法？

问题描述

什么是处理用户要回到那个曾经在一个asp.net应用程序缓存的项目页面的最佳方式？有没有捕捉后退按钮（事件？），并处理缓存方式的好办法？

What's the best way to handle a user going back to a page that had cached items in an asp.net app? Is there a good way to capture the back button (event?) and handle the cache that way?

推荐答案

您可以尝试使用如果这将有助于：

You can try using the HttpResponse.Cache property if that would help:

Response.Cache.SetExpires(DateTime.Now.AddSeconds(60));
Response.Cache.SetCacheability(HttpCacheability.Public);
Response.Cache.SetValidUntilExpires(false);
Response.Cache.VaryByParams["Category"] = true;

if (Response.Cache.VaryByParams["Category"])
{
   //...
}

或者可能可以与<一个完全阻止页面缓存href=\"http://msdn.microsoft.com/en-us/library/system.web.htt$p$psponse.cachecontrol.aspx\">Htt$p$psponse.CacheControl,但其被撤销$ P $赞成上述的缓存属性pcated：

Or could could block caching of the page altogether with HttpResponse.CacheControl, but its been deprecated in favor of the Cache property above:

Response.CacheControl = "No-Cache";

编辑：或者你可以真正，并用手做这一切：

Response.ClearHeaders();
Response.AppendHeader("Cache-Control", "no-cache"); //HTTP 1.1
Response.AppendHeader("Cache-Control", "private"); // HTTP 1.1
Response.AppendHeader("Cache-Control", "no-store"); // HTTP 1.1
Response.AppendHeader("Cache-Control", "must-revalidate"); // HTTP 1.1
Response.AppendHeader("Cache-Control", "max-stale=0"); // HTTP 1.1
Response.AppendHeader("Cache-Control", "post-check=0"); // HTTP 1.1
Response.AppendHeader("Cache-Control", "pre-check=0"); // HTTP 1.1
Response.AppendHeader("Pragma", "no-cache"); // HTTP 1.1
Response.AppendHeader("Keep-Alive", "timeout=3, max=993"); // HTTP 1.1
Response.AppendHeader("Expires", "Mon, 26 Jul 1997 05:00:00 GMT"); // HTTP 1.1
