### Runtime Ping Interval
You can override the ping interval at runtime instead of changing the compile-time macro. Set it to `0` to disable automatic pings entirely.
```cpp
// Server side
httplib::Server svr;
svr.set_websocket_ping_interval(10); // 10 seconds
// Or using std::chrono
svr.set_websocket_ping_interval(std::chrono::seconds(10));
// Client side
httplib::ws::WebSocketClient ws("ws://localhost:8080/ws");
ws.set_websocket_ping_interval(10); // 10 seconds
// Disable automatic pings
ws.set_websocket_ping_interval(0);
```
## Threading Model
WebSocket connections share the same thread pool as HTTP requests. Each WebSocket connection occupies one thread for its entire lifetime.
