I was trying to find out the difference between a socket as a unix file and a socket that is a ip and port.

If I switch something like uwsgi to use a file instead of a port and ip, how do I then access uwsgi as a URL in my browser, since no port is now specified for my flask application.

You can run uwsgi to listen to a TCP/IP port, for example uwsgi --http :80 , if you change it to listen to a Unix socket (for ex: uwsgi --socket :8000 ) then as you said, this is local only, no web service (TCP/IP) is exposed to the Internet and you have to put a web server like nginx in front of uwsgi as 'proxy' that can get the http requests from the outside world (see https://gist.github.com/evildmp/3094281 for a django example instead of Flask)

    This doesn't actually answer the question of using a Unix socket.

  • @larsks It does answer the question. It specifies exactly what you need (nginx or similar) in the middle to access it from a browser. Jun 17 at 5:22
  • It does not provide any example of using a unix socket. The examples in this answer show how to use network sockets. A unix socket is an entry in the filesystem, not a network port.

Browsers don't support making requests to Unix sockets. Here's a feature request that was opened with Chromium, but they responded that they would not be adding support for that use case.
