caching - Nginx return header indicating cache status

Question

In order to make debugging an nginx setup easier it would be nice to add a header to the http response indicating the cache status (HIT/MISS). Is there a way to do this with a simple nginx cache setup such as this?

server {
    # ...
    location / {
        proxy_cache my_cache;
        proxy_pass http://my_upstream;
    }
}

I found basic docs for adding a header using add_header but not how to dynamically change the response based on the cache status.
