When deploying an application with Qodly/4D for the Web, the presence or absence of the qodlyApp.json file, as well as the definition of the startPage property, directly affect how the server responds when accessing the root URL.

If qodlyApp.json exists and startPage is not defined, the server will return a 404 Not Found error when accessing the root URL.

If qodlyApp.json does NOT exist, the server will automatically serve the index.html file

Example of qodlyApp.json:

{
   "webforms.renderer.indexPage": "Date_Intervals",
   "webforms.display-mode": "neutral",
   "webforms.i18n": {
      "supported": [],
      "primary": ""
    }
}
