Response HeaderAllow
Beispiel:
Allow: GET, HEAD, PUT
Original Beschreibung (engl.):
The Allow entity-header field lists the set of methods supported
by the resource identified by the Request-URI. The purpose of this
field is strictly to inform the recipient of valid methods
associated with the resource. An Allow header field MUST be
present in a 405 (Method Not Allowed) response.
Allow = "Allow" ":" #Method
Example of use:
Allow: GET, HEAD, PUT
This field cannot prevent a client from trying other methods.
However, the indications given by the Allow header field value
SHOULD be followed. The actual set of allowed methods is defined
by the origin server at the time of each request.
The Allow header field MAY be provided with a PUT request to
recommend the methods to be supported by the new or modified
resource. The server is not required to support these methods and
SHOULD include an Allow header in the response giving the actual
supported methods.
A proxy MUST NOT modify the Allow header field even if it does not
understand all the methods specified, since the user agent might
have other means of communicating with the origin server.
