Connection Lifecycle Management
Manage WebSocket connection lifecycles, including opening, closing, and unexpected disconnections.
WebSocket Connection Lifecycle
Every WebSocket connection goes through a lifecycle: it opens, stays active for messaging, and eventually closes. Managing these stages is crucial for building robust real-time applications.
Proper lifecycle management helps ensure resources are used efficiently and that your application responds gracefully to various connection events.
The Initial Handshake
Before a WebSocket connection is established, an initial HTTP handshake occurs. The client sends an HTTP request with an Upgrade header, asking to switch protocols.
If the server agrees, it responds with a 101 Switching Protocols status, and the connection transitions from HTTP to WebSocket.
