url_path()

The last path component for the basename of the path to the callback module.

Inherited from LifecycleHandler

__init__(*, filename[, argv, package])

keyword filename

path to a module to load lifecycle callbacks from

modify_document(doc)

on_server_loaded(server_context)

Execute on_server_unloaded` from the configured module (if it is defined) when the server is first started.

on_server_unloaded(server_context)

Execute on_server_unloaded from the configured module (if it is defined) when the server cleanly exits.
