禁止在MVC 3的局部视图缓存 [英] Disable caching on a partial view in MVC 3

问题描述

我有一个局部视图的问题被缓​​存，当它不应该。这部分视图用于在页面上显示的登录/注销。它使用下面的简单code弄清楚要显示的链接

I have an issue with a partial View being cached when it shouldn't be. This partial View is used to display the Logon/Logoff on a page. It uses the simple code below to figure out which link to display

@if(Request.IsAuthenticated) {    
    <a href="@Url.Action("LogOff", "Account", new { area = "" })">Log Off</a> 
}
else {
    <a href="@Url.Action("LogOn", "Account", new { area = "" })">Log On</a>
}

这部分观点是从我MVC3应用程序的所有页面调用，使用

This partial View is called from with all pages in my MVC3 application, using

@Html.Partial("_HeaderView")  

在我的大多数控制器，我有输出缓存定义的，所以我可以把我的缓存内容的优势。

In most of my controllers, I have the output cache defined, so I can take advantage of caching my content.

[OutputCache(Duration = 86400, VaryByParam = "*")]

现在我的问题是，整个页面被缓存的时候我不想局部视图为。这导致错误的行为，其中它有时显示注销时用户没有在等记录是否有缓存所有内容的方式，除了所讨论的局部视图？

Now my issue is that the entire page is being cached when I don't want the partial view to be. This is causing wrong behavior where it sometimes display LogOff is the user is not logged in etc. Is there a way to cache all the content, except for the partial view in question?
