问题描述

我有一个网站，例如twitter，每30秒或更短的时间就会更新一次.网站首页分为三个部分:-

I have a Website something like twitter who are update per 30 seconds or less. the website frontpage have three part:-

左侧面板或右侧部分很少更新，但是右侧部分有随机更改，因此我不需要缓存它们，但是左侧或右侧的所有内容都需要缓存以提高性能.

the leftside panel or right side part rarely to be updated but a section on rightside have random changes so i not need to cache them but everything in leftside or rightside i need to be in cache to improve performance.

列出一些新事物时，中间的栏每隔几秒钟就会发生变化.所以我认为，如果我缓存它们，那么用户将永远不会得到更新，

the middle bar have changes in every few second when some new thing come to listed. so i thing that if i cache them then the user never get update so

当数据库中发生更改时，我如何使用缓存并删除所有缓存.在ASP.NET MVC中做到这一点的任何技巧

推荐答案

您需要使用

You need to use the OutputCacheAttribute or something similar. This action filter "represents an attribute that is used to mark an action method whose output will be cached." When an action updates the database, the resulting view should be cached, because it is overwriting the previously cached data.
