Interface ContentEncodingHeader

All Superinterfaces:

java.lang.Cloneable, Encoding, Header, java.io.Serializable

public interface ContentEncodingHeader
extends Encoding, Header

A ContentEncodingHeader is used as a modifier to the "media-type". When present, its value indicates what additional content codings have been applied to the entity-body, and thus what decoding mechanisms must be applied in order to obtain the media-type referenced by the ContentTypeHeader. The ContentEncodingHeader is primarily used to allow a body to be compressed without losing the identity of its underlying media type.

If multiple encodings have been applied to an entity, the ContentEncodings must be listed in the order in which they were applied. All content-coding values are case-insensitive. Clients MAY apply content encodings to the body in requests. A server MAY apply content encodings to the bodies in responses. The server MUST only use encodings listed in the Accept-Encoding header field in the request. If the server is not capable of decoding the body, or does not recognize any of the content-coding values, it must send a UNSUPPORTED_MEDIA_TYPE Response, listing acceptable encodings in an AcceptEncodingHeader.
