WebSocket Post-Handshake Callback
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Similar to the pre-handshake callback, the HTTP server component also provides a post-handshake callback for WebSocket endpoints. This callback is invoked after the WebSocket handshake is processed.

To use the WebSocket post-handshake callback, you must enable :ref:`CONFIG_HTTPD_WS_POST_HANDSHAKE_CB_SUPPORT` in your project configuration.
