缓存内容仅对非认证用户 [英] Caching content only for non-authenticated users

问题描述

对于一个网站，我想缓存只对谁不认证用户的页面 - 身份验证的用户没有得到缓存的内容（因为他们将被更新，需要马上看到结果）

For a web-site, I want to cache the pages ONLY for users who are not authenticated - authenticated users do not get cached content (since they will be updating and need to see results right away).

我知道如何改变使用VaryByCustom是每个用户缓存：

I know how to vary the cache for each user using VaryByCustom: Link1 Link2

...但我不能想出如何完全关闭缓存身份验证的用户。

...But I can't figure out how to turn off caching entirely for authenticated users.

该怎么办？

修改

下code的，如果已经有来自未认证用户的页面的缓存版中的问题。基本身份验证的用户将被送达事物的未经验证的视图。

The code below has a problem if there is already a cached version of the page from an unauthenticated user. Basically the authenticated user will be served the unauthenticated view of things.

不过，这个环节在这里有解决方案，它的工作原理：<一href=\"http://stackoverflow.com/questions/2109928/how-to-turn-output-caching-off-for-authenticated-users-in-asp-net-mvc\">Link

However, this link here has solution that works: Link
