TWebSocketUpgrader Class

Upgrades an HTTP request to a WebSocket connection.

Remarks

Instances are created by TWebSocketMiddleware and made available in the request context, so applications normally retrieve the IWebSocketUpgrader interface from the context instead of creating this class directly.

Syntax

TWebSocketUpgrader = class(TInterfacedObject, IWebSocketUpgrader);
