How to setup the proxy?

Ionic Framework ionic-v3
6

Hi, the configuration for the proxy is in the 1st post but I’ve changed it to:

"proxies": [
    {
      "path": "/videos-explicativos",
      "proxyUrl": "https://myserver.net/videos-explicativos"
    }
  ]

My Ionic info is:

Ionic:

   ionic (Ionic CLI)  : 4.1.1 (C:\Users\UsuarioDT01\AppData\Roaming\npm\node_modules\ionic)
   Ionic Framework    : ionic-angular 3.9.2
   @ionic/app-scripts : 3.1.10

Cordova:

   cordova (Cordova CLI) : not installed
   Cordova Platforms     : not available
   Cordova Plugins       : cordova-plugin-ionic 4.1.7, cordova-plugin-ionic-keyboard 2.1.2, cordova-plugin-ionic-webview 2.0.2, (and 12 other plugins)

System:

   Android SDK Tools : 26.1.1 (C:\Users\UsuarioDT01\AppData\Local\Android\Sdk)
   NodeJS            : v8.11.1 (C:\nodejs\node.exe)
   npm               : 5.6.0
   OS                : Windows 10

Also I don’t understand why the request is being sent as OPTION when it’s a GET in both server and client.
