What's the difference between the + and * with HttpListener

Question

I want to implement a HttpListener that listen to a specific port, but i don't understand why i should use:

-http://+:8080/
or
-http://*:8080/
or
-http://127.0.0.1:8080/ <-> http:// localhost:8080

thanks in advance

Answer 1

your localhost resolves to 127.0.0.1

and here is a good answer for what you are asking essentially :

https://*:8080: Receieve all https requests on port 8080 that are not already being handled by some other HTTPListener

https ://+:8080: Receive all https requests on port 8080 even if they're already handled by another HTTPListener
