public final class Allow

Represents a parsed Allow HTTP response header.

Valid methods for a specified resource. To be used for a 405 Method not allowed.

Example

Allow: GET, HEAD

RFC2616 Specification

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.
