POST
This method requests that the origin server accept the entity enclosed in the request as a new subordinate of the
resource identified by the Request-URI.
The actual action performed by the POST method is determined by the origin server and usually is Request-URI
dependent.
Responses to POST method are not cacheable, unless the response includes appropriate Cache-Control or Expires
header fields.
PUT
This method requests that the enclosed entity be stored under the supplied Request-URI. If another entity exists
under specified Request-URI, the enclosed entity should be considered as updated (newer) version of that residing on
the origin server. If the Request-URI is not pointing to an existing resource, the origin server should create a resource
with that URI.
If the request passes through a cache and the Request-URI identifies one or more currently cached entities, those
entries should be treated as stale. Responses to this method are not cacheable.
TRACE
This method invokes 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 0 in the request. A
TRACE request must not include an entity.
Responses to this method MUST NOT be cached.
