Host, Port, URL, TLS, IPVersion and Active open a synchronous or asynchronous connection. Connect/Disconnect block the caller, Start/Stop run on a worker thread.
HeartBeat sends WebSocket ping frames on a timer; WatchDog automatically reconnects after an unexpected drop. OnBeforeHeartBeat and OnBeforeWatchDog let you customise each cycle.
TLSOptions selects the IOHandler (OpenSSL or SChannel), TLS version (1.0–1.3) and ALPN; Proxy routes the handshake through HTTP or SOCKS; Authentication handles Basic / Bearer / custom schemes.
WriteData sends a text frame with optional fragmentation; WriteAndWaitData blocks until the peer answers; Ping sends a ping frame. OnMessage, OnBinary and OnFragmented deliver incoming data.
Extensions.PerMessage_Deflate negotiates RFC 7692 compression; Throttle caps bits-per-second in either direction; QueueOptions serialises Text / Binary / Ping writes on the connection thread.
LogFile dumps raw inbound and outbound traffic to disk; NotifyEvents selects how events are dispatched to the main thread; OnException, OnError and OnHandshake surface protocol-level details.
