All Known Implementing Classes:

DirectRouter, PathRouter, ProtocolRouter

public interface Router

The Router interface represents a means of routing a session initiating request to the correct service. Typically a service is chosen based on the sub-protocol provided in the initiating request, however it can be chosen on any criteria available in the request. An initiating request must contain a Connection header with the websocket token according to RFC 6455 section 4.2.1. If the request does not contain this token it is treated as a normal request and a Service will not be resolved.

If a service has been successfully chosen from the initiating request the the value of Sec-WebSocket-Protocol will contain either the chosen protocol if a match was made with the initiating request or null to indicate a default choice.
