Package jain.protocol.ip.sip.header Description

This package contains the classes representing SIP headers.

Headers can be one of the following types:

• GeneralHeader - can be in RequestMessage or ResponseMessage
• RequestHeader - can only be in RequestMessage
• ResponseHeader - can only be in ResponseMessage
• EntityHeader - describes Message body or resource

Messages may contain multiple instances of certain Headers. The order of these Headers within a Message is significant. The order of all Headers within a Message is also significant. Additionally, Headers which are hop-by-hop must appear before any Headers which are end-to-end. Proxies should not reorder Headers. Proxies add ViaHeaders and may add other hop-by-hop Headers. They can modify certain Headers, such as MaxForwardsHeaders and "fix up" the ViaHeaders with "received" parameters. Proxies must not alter any Headers that are authenticated.

Other Headers can be added as required; a server must ignore Headers that it does not understand. A proxy must not remove or modify Headers that it does not understand.
