What's the difference between http://*:80 and http://+:80

Question

In learning about Web Deploy I came across some netsh.exe commands that talk about http://+:80 and http://*:80. What do those mean?

Answer 1

In a few basic words, "*" handles requests if no one else did and "+" handles requests even if it was handled by any other handler.

A good example taken from https://stackoverflow.com/a/9459679/6375269

http://*:8080/: Receive all HTTP requests on port 8080 that are not already being handled by some other HttpListener.

http://+:8080/: Receive all HTTP requests on port 8080 even if they're already handled by another HttpListener.
