Prefix query parameter representing protocol header with protocol name.

[flowersinthesand]

How to represent protocol header depends on each transport but now all supported transports including even socket are using URI's query component. However because user may use query as well to attach some information according to the original purpose of query as a component of URI, it might conflict with ones used to represent protocol header.

To avoid confusion, every query parameter representing protocol header should be prefixed with their protocol name such as cettia or cettia-transport. For example, from the point of view of http server, a URI of one of requests belonging to http streaming transport

http://localhost:8080/cettia/?user-foo=bar&transport=stream&id=${transport.id}&sid=${socket.id}

should be rewritten to

http://localhost:8080/cettia/?foo=bar&cettia-transport-name=stream&cettia-transport-id=${transport.id}&cettia-id=${socket.id}

• sid to cettia-id
• heartbeat to cettia-heartbeat
• _heartbeat tocettia-_heartbeat
• id to cettia-transport-id
• when to cettia-transport-when
• transport to cettia-transport-name
• sse to cettia-transport-sse
• jsonp to cettia-transport-jsonp
• callback to cettia-transport-callback
