Using server hooks
------------------

If you wish to include server hooks in your custom application, you can specify a function in the config options. Here is an example with the `pre_fork` hook:

.. code-block:: python

def pre_fork(server, worker):
print(f"pre-fork server {server} worker {worker}", file=sys.stderr)

# ...
if __name__ == '__main__':
options = {
'bind': '%s:%s' % ('127.0.0.1', '8080'),
'workers': number_of_workers(),
'pre_fork': pre_fork,
}
