This is a request to register the text/event-stream media type by reference to the Server-Sent Events specification: http://www.w3.org/TR/eventsource/#text-event-stream --------------------------------------------------------------------------- Type name: text Subtype name: event-stream Required parameters: No parameters Optional parameters: charset The charset parameter may be provided. The parameter's value must be "utf-8". This parameter serves no purpose; it is only allowed for compatibility with legacy servers. Encoding considerations: 8bit (always UTF-8) Security considerations: An event stream from an origin distinct from the origin of the content consuming the event stream can result in information leakage. To avoid this, user agents are required to apply CORS semantics. [CORS] Event streams can overwhelm a user agent; a user agent is expected to apply suitable restrictions to avoid depleting local resources because of an overabundance of information from an event stream. Servers can be overwhelmed if a situation develops in which the server is causing clients to reconnect rapidly. Servers should use a 5xx status code to indicate capacity problems, as this will prevent conforming clients from reconnecting automatically. Interoperability considerations: Rules for processing both conforming and non-conforming content are defined in the Server-Sent Events specification. Published specification: The Server-Sent Events specification is the relevant specification. Applications that use this media type: Web browsers and tools using Web services. Additional information: Magic number(s): No sequence of bytes can uniquely identify an event stream. File extension(s): No specific file extensions are recommended for this type. Macintosh file type code(s): No specific Macintosh file type codes are recommended for this type. Person & email address to contact for further information: Michael[tm] Smith <mike@w3.org> Intended usage: Common Restrictions on usage: This format is only expected to be used by dynamic open-ended streams served using HTTP or a similar protocol. Finite resources are not expected to be labeled with this type. Author: Ian Hickson <ian@hixie.ch> Change controller: W3C Fragment identifiers have no meaning with text/event-stream resources. --------------------------------------------------------------------------- -- Michael[tm] Smith http://people.w3.org/mike
