http:shutdown-server &optional server[Function]

Shutdown the server, removing all port listners. If the server is using a task queue then it is not shutdown because it may have been shared with other servers which are still running, so pending tasks may continue to execute until done. For the default task queue, see thread:shutdown-task-queue to shutdown the task queue. The server may be later restarted by starting new listeners.
