我要建立在网​​络都失效和 cachecontrol 和 httpExpires 头。配置
通过对这个问题下面的答案
<一href=\"http://stackoverflow.com/questions/5946894/whats-the-difference-expires-and-cache-controlmax-age\">What's区别过期和缓存控制：最大年龄

I want to set up both expires and cachecontrol and httpExpires headers in web.config by following the answer on that question What's the difference Expires and Cache-control:max-age?

     <system.webServer>
        <staticContent>
            <clientCache cacheControlCustom="public" cacheControlMaxAge="12:00:00" cacheControlMode="UseMaxAge" />
            <clientCache cacheControlCustom="public" httpExpires="Tue, 19 Jan 2038 03:14:07 GMT" cacheControlMode="UseExpires" />
        </staticContent>
    </system.webServer>

但出于某种原因图像变得不，当我这样做用。

But for some reason images became not available when I am doing that.

我已经有了无法加载资源：服务器在每个图像负荷500（内部服务器错误）错误的状态回应（我可以看到，在错误浏览器开发工具的控制台）。

I've got Failed to load resource: the server responded with a status of 500 (Internal Server Error) error on each image load (I can see that errors in browser dev tools console).

我想我配置错了？

这将通过剩下的只有单一的一个，如果我评论的任何 clientCache 的工作节

It would work if I comment any of clientCache section by leaving only single one

如何解决？

推荐答案

这<一个href=\"http://stackoverflow.com/questions/20826035/how-to-set-up-both-httpexpires-and-cachecontrol-headers\">IIS客户端缓存页面指出，虽然过期和max-age的设置偏于analagous，最大年龄指令优先于过期。然而，当一个max-age的clientCache条目并行使用与IIS生成HTTP 500错误过期clientCache条目。

This IIS Client Cache page states that 'While the "Expires" and "max-age" settings are somewhat analagous, the "max-age" directive takes priority over "Expires"'. However, IIS generates HTTP 500 errors when one "max-age" clientCache entry was used in parallel with an "Expires" clientCache entry.

在过期，并在IIS调整设置常用标题当最大年龄是相互排斥彼此。您可以使用一个或另一个，但不能两者兼得。

The "Expires" and "max-age" are mutually exclusive of one another when adjusting the "Set Common Headers" in IIS. You can use one or the other, but not both.

其他高速缓存指令可应用于Web.config中的子文件夹或特定文件。看到这个<一个href=\"http://stackoverflow.com/questions/2195266/how-to-configure-static-content-cache-per-folder-and-extension-in-iis7\">stackoverflow在IIS7配置缓存中的内容页面。

Other cache directives can be applied to subfolders or specific files in Web.config. See this stackoverflow page on configuring cache content in IIS7.
