有几个关于利用浏览器缓存的问题，但是我没有找到任何关于如何在ASP.NET应用程序中做到这一点的有用的东西。Google的Pagespeed告诉我们这是最大的性能问题。到目前为止，我在web.config中做到了这一点

代码语言：javascript
复制
<system.webServer>
  <staticContent>
    <!--<clientCache cacheControlMode="UseExpires"
            httpExpires="Fri, 24 Jan 2014 03:14:07 GMT" /> -->
    <clientCache cacheControlMode="UseMaxAge" cacheControlMaxAge="7.24:00:00" />
  </staticContent>
</system.webServer>

注释代码可以工作。我可以将expire设置为将来的某个特定时间，但我无法设置cacheControlMaxAge来设置从现在起多少天后静态内容将被缓存。它不起作用。我的问题是：

我该怎么做呢？我知道可以只为特定的文件夹设置缓存，这将是一个很好的解决方案，但它也不起作用。应用程序托管在Windows Server 2012上，在IIS8上，应用程序池设置为经典。

当我在web配置中设置了这个代码后，我得到了72页的速度(之前是71页)。50个文件未缓存。(现在49)我想知道为什么，我只是意识到有一个文件实际上被缓存了(svg文件)。不幸的是，png和jpg文件不是。这是我的web.config

编辑：如果我设置了确切的过期日期，缓存正在工作，但不是jpg，gif....only是png

EDIT2:如果我像这样设置cacheControlCustom="public"：

代码语言：javascript
复制
<clientCache cacheControlCustom="public" 
cacheControlMode="UseMaxAge" cacheControlMaxAge="7.00:00:00" />

缓存正在工作，但仍然，不适用于jpeg和gif；它只适用于svg和png。

使用这个。这对我很有效。

使用上述方法，静态内容文件将在浏览器中缓存10天。有关<clientCache>元素的详细信息可以在here中找到。

还可以使用<location>元素定义特定文件的缓存设置：

代码语言：javascript
复制
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
  <location path="path/to/file">
    <system.webServer>
