/// @assertion HttpHeaders defaultResponseHeaders
/// Default set of headers added to all response objects.

/// By default the following headers are in this set:

///  Content-Type: text/plain; charset=utf-8
///  X-Frame-Options: SAMEORIGIN
///  X-Content-Type-Options: nosniff
///  X-XSS-Protection: 1; mode=block

/// If the Server header is added here and the serverHeader is set as well then
/// the value of serverHeader takes precedence.
