The TRACE HTTP method is asking for a trace of the actual request, so the client can see exactly what is being recieved by the server. This is used only for testing and troubleshooting.
OPTIONS asks for a list of the http methods to which the requested resource can respond. For example, "Allow: OPTIONS, TRACE, GET, HEAD, POST".
