I have a virtual directory on IIS7.5, it has .mp4 files.

I want to enable caching at folder level, so that videos can play without buffering. Can the following "web.config" be used? I want to place the "Web.config" inside the folder.

```
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
  <system.webServer>
    <staticContent>
      <clientCache cacheControlMode="UseMaxAge" cacheControlMaxAge="01:00:00" />
    </staticContent>
  </system.webServer>
</configuration>

```

I also do want to limit the cache to 1GB, how do I achieve this?
