Lets have a look at placing a web.config inside of a directory and IIS will apply that functionality specifically in that directory.
Place this web.config file inside your Content folder and set the cacheControlMaxAge to whatever you want.
This one file will provide a speed boost to your readers on your site. This will cache the entire Content folder.
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<staticContent>
<clientCache cacheControlMode="UseMaxAge" cacheControlMaxAge="1.00:00:00" />
</staticContent>
</system.webServer>
</configuration>
If you don't want the entire folder with subdirectories cached? Place it into another folder that contains static content.
