    38   * The HTTP TRACE method is defined in section 9.6 of
    39   * <a href="http://www.ietf.org/rfc/rfc2616.txt">RFC2616</a>:
    40   * <blockquote>
    41   *  The TRACE method is used to invoke a remote, application-layer loop-
    42   *  back of the request message. The final recipient of the request
    43   *  SHOULD reflect the message received back to the client as the
    44   *  entity-body of a 200 (OK) response. The final recipient is either the
    45   *  origin server or the first proxy or gateway to receive a Max-Forwards
    46   *  value of zero (0) in the request (see section 14.31). A TRACE request
    47   *  MUST NOT include an entity.
