title: How do I set the cachability of static files in IIS?
body: <p>I have some static images in a folder on my IIS 6-based website that I want to be downloaded as little as possible (to preserve bandwidth). I've set the Content Expiration to expire after 30 days. Is there anything else I can do in IIS to try to maximize the caching by browsers, proxy, and gateway caches?</p>
  
  <p>Such as adding a Cache-Control header? Anything else?</p>
