Will the WebSocket connection persist if the user closes or minimizes the browser window?

When a user closes or minimizes a browser window, the WebSocket connection is usually interrupted.

Reasons:

• When the browser window is closed, the process supporting WebSocket terminates, and the connection is closed.
• When minimizing the window (for example, switching to the background), the browser may suspend active connections or limit their operation to save resources.

On iOS, if the app is running in a browser, the WebSocket connection may be terminated or suspended when the tab is minimized or when switching to another app.

To maintain the connection, mechanisms such as reconnection upon activity resumption or background tasks are usually used, if the platform and browser support it.
