: Localhost (IP 127.0.0.1) is the ultimate digital mirror. It’s where code lives before it's "real" to anyone else. Port 11501 is simply a specific "door" or channel on your computer often used by specialized software—like the Khajane 2 system or custom GUI applications—to communicate internally.
localhost:11501 refers to a specific port address on your own computer, typically used for local development, custom services, or debugging.
It may be a custom port assigned by a developer for testing a web application, API, or database management tool like dbFront .
Now nginx (free web server) is available on localhost:11501.
