Configure NetScaler LAN proxy using DLL
Supported on: All Citrix Workspace supported platforms
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) REG Builder
BETAConfigure the state and elements to generate .reg, PowerShell, Intune, and SCCM outputs.
These exports replicate the policy's registry effect. Editing the registry directly is not the same as applying the GPO through the management console (no gpupdate, no central reporting). Test before production; HKLM changes require administrator rights.
