Interface RequestUpgradeStrategy

public interface RequestUpgradeStrategy
A strategy for upgrading an HTTP request to a WebSocket session depending on the underlying network runtime.

Typically there is one such strategy for every ServerHttpRequest and ServerHttpResponse type except in the case of Servlet containers for which the standard Java WebSocket API JSR-356 does not define a way to upgrade a request so a custom strategy is needed for every Servlet container.
