Following the solution to configure Microsoft Edge Chromium.
Description
To figure out the required values for the configuration, the traffic between the Microsoft Edge Chromium and the Citrix NetScaler Gateway must be analyzed. In my environment, I analyzed the traffic with the Microsoft Edge Chromium Developer Tools. You can observe the call to start the nglauncher.exe in the HTTP header request of the Citrix NetScaler page.
The “Request URL:” part includes the desired configuration, for the further steps. You can configure the setting globally with GPO (Microsoft Edge Chromium ADMX ), or locally in the registry of the end user device.
