public class ContentEncoding extends SIPHeader implements ContentEncodingHeader
From HTTP RFC 2616
14.11 Content-Encoding
The Content-Encoding entity-header field 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 Content-Type header field. Content-Encoding is
primarily used to allow a document to be compressed without losing
the identity of its underlying media type.
Content-Encoding = "Content-Encoding" ":" 1#content-coding
Content codings are defined in section 3.5. An example of its use is
Content-Encoding: gzip
The content-coding is a characteristic of the entity identified by
the Request-URI. Typically, the entity-body is stored with this
encoding and is only decoded before rendering or analogous usage.
However, a non-transparent proxy MAY modify the content-coding if the
new coding is known to be acceptable to the recipient, unless the
"no-transform" cache-control directive is present in the message.
If the content-coding of an entity is not "identity", then the
response MUST include a Content-Encoding entity-header (section
14.11) that lists the non-identity content-coding(s) used.
If the content-coding of an entity in a request message is not
acceptable to the origin server, the server SHOULD respond with a
status code of 415 (Unsupported Media Type).
If multiple encodings have been applied to an entity, the content
codings MUST be listed in the order in which they were applied.
Additional information about the encoding parameters MAY be provided
by other entity-header fields not defined by this specification.
