Computer Configuration\Administrative Templates\Citrix Components\Citrix Workspace\Network routing\Proxy Description
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.
Registry
HKLM
Software\Policies\Citrix\ICA Client\Engine\Network Routing\Proxy\NetScaler LAN Proxy Value name: DynamicProxyEnabled
Enabled: DynamicProxyEnabled = 1
Disabled: DynamicProxyEnabled = 0
This policy sets several registry values:
ProxyChooserDLL Enabled:
ProxyChooserDLL = Disabled:
ProxyChooserDLL = (deleted) Export Builder
BETAConfigure the state, scope and options, then generate .reg, PowerShell, Intune and SCCM outputs — or add the setting to a multi-setting collection.
These exports write the registry — this is not a managed GPO. ⓘ
