Interface SIPIfMatchHeader

All Superinterfaces:

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

public interface SIPIfMatchHeader
extends Header

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

The SIP-If-Match header is used by a client (event state publisher) in a PUBLISH request, to update previously published event state. The value is obtained from the server in a SIPETagHeader in a 2xx response to a previous PUBLISH.

Sample syntax:
SIP-If-Match: dx200xyz

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