Title: Removing Content-Type and Accept headers

The `Content-Type` request header is unnecessary because these requests have no representations (bodies) to them.
The `Accept` request header is unnecessary because the responses to these requests are not expected to have any representations (bodies) to them. In fact, supplying a strict `Accept` header like `Accept: application/json` has empirically shown to cause a `406 Not Acceptable` response.
