-# Setting Response Headers
+# CDN Response Headers
 
 For applications with UI, static assets such as HTML, Javascript, css, and images are served by the Content Content Delivery Network through the `adobeio-static.net` domain. App Builder has supported setting response headers for this static content since aio-cli version 9.3.0.
 
 This feature applies to any App Builder applications with UI, and is helpful for use cases such as:
 
 - Setting `CORS` Headers to enforce access policies
+- Controlling web-assets caching behavior via [`Cache-Control` headers](https://developer.mozilla.org/en-US/docs/Web/HTTP/Reference/Headers/Cache-Control)
 - Enabling `Content Security Policy` for assets
 - Adding any `custom headers` required by the application UI

         Content-security-policy: default-src 'self'

+        # cache all png files for 1 hour at CDN level and 1 minute in browser
+        cache-control: s-maxage=3600, max-age=60
 ```
 
 Once headers are added, they can be deployed with the app using the `aio app:deploy` command. Note that the paths specified in rules are relative to the distributable folder created after the application build, and not to the application root.
