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