      Do request with not allowed HTTP method, e.g. using TRACE (e.g. using telnet): TRACE / HTTP/1.1 Host: localhost

      According to RFC for HTTP/1.1 the server should provide Allow header in case of responding with 405 [1], but Undertow doesn't send it.

      10.4.6 405 Method Not Allowed

      The method specified in the Request-Line is not allowed for the
      resource identified by the Request-URI. The response MUST include an
      Allow header containing a list of valid methods for the requested
      resource.
