## Overview

A handler which sets the response content type automatically according to the best `Accept` header match. The header is set only if:

- no object is stored in the routing context under the name DEFAULT_DISABLE_FLAG
- a match is found
- the header is not present already
- content length header is absent or set to something different than zero
