UNIX socket for listen_addr

webserver:
  listen_addr: "127.0.0.1"
  listen_port: 8080

can I have UNIX socket for speed and security(so that others cannot try to use it)?

e.g.,

webserver:
  listen_addr: "/tmp/ricky_certstream.sock" <--- the path must ends with ".sock"
  listen_port: 0 <--- when using UNIX socket, there's no port to use

When certstream starts:

1. Read config,
2. If the listen_addr is UNIX socket, check the existence of the file
3. If the sock file is exist, then certstream is running, exit.
4. Listen on sock file

Thanks for the suggestion. That should be doable. I don't think we should use the same config variables as for the webserver. Another pair of options would make for a better solution imho.

I am currently a bit low on time but I try to implement file system sockets.

I am currently implementing kafka support. I restructured the code a bit with that feature and made it possible to add various kinds of connectors, next to websockets. That means unix sockets can easily be implemented next.
