HTTP TRACE Method
Information about the HTTP TRACE method.
HTTP TRACE
Trace the route to the resource, allowing debugging to occur. The results will be returned in the response body.
- Request Body
- Data in a request body should not be sent. While not forbidden, the behaviour is undetermined and different servers may react differently. 
- Response Body
- A response body will not be returned. 
- Cache
- The response cannot be cached. 
- Safe
- The request should not alter the state of the server - it should be read-only. This is not enforced by the server, and a common mistake is for a safe request to cause a change. 
- Idempotent
- The request should not cause any side-effects on the server and it should be possible to issue the same request several times with the server being left in the same state. - This is not enforced by the server and a common mistake is for an idempotent request to change the server state.
