169. What is the response body of HTTP status code 304?

The response body of HTTP status code 304 (Not Modified) is empty. The server sends this status code to indicate that the requested resource has not been modified since the last time it was accessed, and therefore the browser can use the cached version of the resource instead of downloading it again.
