Use Host to Client Redirection policy to redirect all URLs from the VDA to the Client. This is useful when redirection fails when the URL is not added to ValidSites Registry, but Customer wants to redirect a long list of URLs but doesn't mind redirecting all URLs.
As per our Product Documentation, to enable host-to-client redirection for a specific set of websites, create a registry key and values on the server VDA.
Key: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\SFTA
Value name: ValidSites
Value type: REG_MULTI_SZ
If we want to redirect all URLs, we can use a Wildcard, so set the value of ValidSites to *.
