+-   **Status Code:** You are able to configure if the redirect should redirect to an url or just return a custom status code of your choice. Example `"RedirectUrl": "-> 418"` will return the status code 418 (I'm a teapot :) )
 
 ## Configuration
 Routes are managed via a configuration file, `/data/config.json`. You can define paths and their corresponding URLs in this file. The application automatically normalizes routes to handle both trailing and non-trailing slashes.
