Citrix Workspace app supports session launches using the NetScaler LAN proxy. If both static proxy and dynamic proxies are configured, the dynamic proxy configuration takes precedence. You can configure Dynamic proxy: Select the Configure NetScaler LAN proxy using DLL policy. Select Enabled and then provide the full path to the DLL file. For example, C:\Workspace\Proxy\ProxyChooser.dll. Click Apply and OK.
