The type of response is always dependent on the type of request and how you should render your output. Humans making a direct browser request will typically want an HTML page in response whereas a remote computer or AJAX response will generally want a native data format such as JSON or XML in response.

The next chapter delves deeper into dealing with REST-based requests and helps you dynamically respond to these requests based on content negotiations.
