WebSocket library for modern and legacy platforms.
Rebex WebSocket is a .NET component that enables applications to connect to WebSocket servers and exchange messages over persistent network connections. Developers can integrate real time communication into software that interacts with WebSocket based services, APIs, or event driven platforms.

WebSocket Client Protocol

Implements the WebSocket protocol for applications that need to connect to WebSocket servers. Software can establish persistent connections with remote services and exchange messages using the standard WebSocket communication model.

Persistent WebSocket Connections

Allows applications to maintain a continuous connection with a WebSocket server after the initial handshake process.

Bidirectional Messaging with WebSocket Servers

Supports message exchange between the application acting as a WebSocket client and the connected server.

WebSocket Handshake Handling

Manages the HTTP upgrade handshake required to establish a WebSocket connection. The component performs the protocol negotiation needed to transition from HTTP communication to the WebSocket messaging protocol.

Message and Frame Processing

Provides functionality for sending and receiving WebSocket messages and handling the underlying protocol frames. Applications can process incoming data, construct outgoing messages, and manage message flow within the connection.

Connection Lifecycle Management

Handles the lifecycle of WebSocket connections including establishing connections, monitoring connection state, and detecting when a session is closed or interrupted. Applications can respond to these events within their networking logic.

Support for Secure WebSocket Connections

Supports communication with WebSocket servers over encrypted connections when used with TLS. This enables applications to connect to secure WebSocket endpoints while protecting data transmitted across networks.
