Interface SIPETagHeader

All Superinterfaces:

Cloneable, Header, Serializable

public interface SIPETagHeader
extends Header

This interface represents the SIP-ETag header, as defined by RFC3903.

The SIP-ETag header is used by a server (event state collector) in a 2xx response to PUBLISH in order to convey a unique entity tag for the published state. The client may then use this tag in a SIPIfMatchHeader to update previously published state.

Sample syntax:
SIP-ETag: dx200xyz

A server must ignore Headers that it does not understand. A proxy must not remove or modify Headers that it does not understand.
