Simple LAN filesharing with WebDAV

WebDAV is both an overlooked and quite popular way to access and edit files remotely across a wide range of operating systems. Yes it's web stuff, again, but surprisingly fast, lightweight, and that can recover quite well on unstable networks or when the server has to be restarted or has gone for lunch. A reason why it may be overlooked is possibly because it's often associated with sausage factories like own/nextcloud, or standalone implementations that are not particularly exciting. There is however a not very well known way to run a very simple and lightweight WebDAV server with lighttpd.
