You can use your web proxy to launch Reflection for the Web sessions. To configure web proxy settings centrally, use the provided PowerShell script.
The PowerShell script generates a transform (*.mst) file that can be used to customize your installation. The script enables you to manage the settings that would otherwise need to be accessed on each workstation.
While the default network settings for the Reflection for the Web Launcher may work, they might need to be adjusted for a more complex network environment, such as with a web proxy.
