Use this policy to control how the client presents local applications inside a hosted desktop. Local App Access enables the integration of locally installed applications within a hosted desktop. When users launch locally installed applications using shortcuts, applications appear to be running on their hosted desktop even though it is running on their local device. When this policy is enabled, client presents locally installed applications inside hosted desktop as shortcuts. When disabled, client doesn't present local apps inside hosted desktop. URL redirection is also disabled. Allow URL Redirection: When this is checked, client allows URLs to be redirected from hosted desktop browser to locally installed browser or vice versa. URL blacklist and whitelist on host determine which URLs would be redirected. Browser add-ons, extensions and plugins required for this feature would also need to enable. When unchecked, URLs are not redirected from hosted desktop to client or vice versa. Browser add-ons, extensions and plugins are not disabled.
