WebUrlTrace Function

Action

Sends a TRACE request to the HTTP/1.1 server. The TRACE method is used to invoke a remote, application-layer loopback 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. Use of the Max-Forwards header field allows the client to limit the length of the request chain; this is useful for testing a chain of proxies forwarding messages in an infinite loop. If successful, the response SHOULD contain the entire request message in the entity body, with a Content-Type of "message/http".
