Prevent storing persistent cookies

Supported on: All Citrix Workspace supported platforms

Description

This policy disallows storing persistent cookies on stores that use WebView authentication. This policy is effective even when you select the option to store credentials. Enabled indicates that the cookies are not stored or used across sessions. The user credentials are not saved. Also, Citrix Workspace app does not clear the Internet Explorer (IE WebBrowserControl) cookies. Disabled or Not Configured indicates that the persistent cookies are stored and credentials are saved during authentication.

REG Builder

BETA

Configure 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.
