在浏览器关闭中删除缓存项 [英] Removing Cache item on Browser Close

问题描述

嗨



我目前有一些代码可以在用户登录应用程序时创建缓存项目。



我想知道如果用户在没有注销的情况下关闭浏览器，我将如何删除此缓存项？

Hi

I currently have some code which creates a cache item when a user signs into the application.

I would like to know how would i be able to remove this cached item if the user closes the browser without signing out?

推荐答案

你无法处理在许多浏览器中一致地关闭按钮事件。

因此，最好设置缓存数据的到期时间。

例如，当您登录时，您可以设置缓存过期到30.

Response.Cache.SetExpires（DateTime.UtcNow.AddMinutes（30））;



另一种方法可能是有一个注销按钮并添加以下代码 -

You cannot handle the close button event consistently across many browsers.
As a result, it may be best to set an expiry on cache data.
For e.g.when you logon, you could set the cache expire to 30.
Response.Cache.SetExpires(DateTime.UtcNow.AddMinutes(30));

Another approach could be to have a logout button and add the following code -

Response.Cache.SetExpires(DateTime.UtcNow.AddMinutes(-1));
 Response.Cache.SetCacheability(HttpCacheability.NoCache);
 Response.Cache.SetNoStore();
