    .. attention::

        Since PyWebIO v1.4, in :ref:`server mode <server_mode>`, it&#x27;s no need to call this function manually,
        PyWebIO will automatically hold the session for you when needed.
        The only case to use it is to prevent the application from exiting in script mode.

    In case you use the previous version of PyWebIO (we strongly recommend that you upgrade to the latest version),
    here is the old document for ``hold()``:

        After the PyWebIO session closed, the functions that need communicate with the PyWebIO server
        (such as the event callback of `put_buttons()` and download link of `put_file()`) will not work.
        You can call the ``hold()`` function at the end of the task function to hold the session,
        so that the event callback and download link will always be available before the browser page is closed by user.
