    The request/response headers object.

    Key-value pairs of header names and values. Header names are lower-cased.

    1. // Prints something like:
    2. //
    3. // { 'user-agent': 'curl/7.22.0',
    4. //   host: '127.0.0.1:8000',
    5. //   accept: '*/*' }
    6. console.log(request.headers);

    See [HTTP/2 Headers Object][].

    In HTTP/2, the request path, host name, protocol, and method are represented as special headers prefixed with the : character (e.g. ':path'). These special headers will be included in the request.headers object. Care must be taken not to inadvertently modify these special headers or errors may occur. For instance, removing all headers from the request will cause errors to occur:

    1. removeAllHeaders(request.headers);
    2. assert(request.url);   // Fails because the :path header has been removed
