问题描述
我工作的一个asp.net MVC的Web应用程序，我需要知道，如果有确定的OutputCache时，我的操作方法如下任何差异： -
I am working on an asp.net MVC web application and I need to know if there are any differences when defining the OutputCache for my action methods as follow:-
[OutputCache(Duration = 0, Location = OutputCacheLocation.Client, VaryByParam = "*")]
VS
[OutputCache(NoStore = true, Duration = 0, Location="None", VaryByParam = "*")]
VS
[OutputCache(NoStore = true, Duration = 0, VaryByParam = "*")]
将在上述的三个设置prevent缓存中的数据，或每个方面都有不同的意义？
Will all the above three setting prevent caching the data , or each on have different meaning ?
第二个问题是定义持续时间= 0 ＆放大器之间的主要区别; NoStore = TRUE ？将两者prevent缓存？
谢谢
Second question what is the main difference between defining duration=0 & NoStore=true ? will both of them prevent caching ?Thanks
推荐答案
的 NoStore 属性被用来通知代理服务器和浏览器，他们不应该存储的永久副本缓存的内容通过设置缓存控制：无店请求头中
The NoStore property is used to inform proxy servers and browser that they should not store a permanent copy of the cached content by setting Cache-Control: no-store within the request header.
时间只需指定多久控制器操作的内容应该被缓存，例如持续10秒。这将设置的Cache-Control：max-age的来> = 0并且还设置了过期头到有效的时间戳。
Duration simply specifies how long the content of the controller action should be cached, e.g. 10seconds. This will set the Cache-Control: max-age to >= 0. And also sets the Expires header to a valid timestamp.
要您最初的问题，不，三个变化不具有相同的含义。
To your initial question, no, the three variations do not have the same meaning.
[OutputCache(Duration = 0, Location = OutputCacheLocation.Client, VaryByParam = "*")]
创建缓存头像这样
create a cache-header like this
Cache-Control: private, max-age=0
Expires: Fri, 03 Jan 2014 12:32:15 GMT
[OutputCache(NoStore = true, Duration = 0, Location="None", VaryByParam = "*")]
创建下列高速缓存头：
creates the following cache-header:
Cache-Control: no-cache, no-store
Pragma: no-cache
Expires: -1
这基本上是要看到，如果你想通过各种手段prevent缓存内容。的VaryByParam是（至少在MVC5）可选，默认为*反正，所以你可以简单地使用 [的OutputCache（NoStore = TRUE，位置= OutputCacheLocation.None）] 来代替。
This is basically what you want to see if you want to prevent caching by all means. VaryByParam is optional (at least in MVC5) and the default is "*" anyways, so you can simply use [OutputCache(NoStore = true, Location = OutputCacheLocation.None)] instead.
[OutputCache(NoStore = true, Duration = 0, VaryByParam = "*")]
甚至造成公众缓存控制...
even creates a public cache control...
Cache-Control: public, no-store, max-age=0
Expires: Fri, 03 Jan 2014 12:36:38 GMT
关于被如此好的帖子，其中讨论的max-age=0和无缓存等。
在结束所有三个威力prevent缓存的数据，但仍然有不同的含义。
At the end all three might prevent caching your data but still have different meanings.
