TRACE
The HTTP TRACE method performs a message loop-back test along the path to the target resource, providing a useful debugging mechanism.
The final recipient of the request should reflect the message received, excluding some fields described below, back to the client as the message body of a 200 (OK) response with a Content-Type of message/http. The final recipient is either the origin server or the first server to receive a Max-Forwards value of 0 in the request.
| Request has body | No |
|---|---|
| Successful response has body | No |
| Safe | Yes |
| Idempotent | Yes |
| Cacheable | No |
| Allowed in HTML forms | No |
