With agent-to-client redirection, Horizon Agent sends the URL to Horizon Client, which opens the default application for the protocol in the URL.
To enable agent-to-client redirection, perform the following configuration tasks.
Ensure the URL content redirection feature is enabled in Horizon Agent in the master image VM, as described in the prerequisites section in Create a URL Redirection Customization and Assign it to Users.
Apply the URL Content Redirection group policy settings to your remote desktops and applications. See Add the URL Content Redirection ADMX Template to a GPO.
Configure group policy settings to indicate, for each protocol, how the Horizon Agent should redirect the URL. See URL Content Redirection Group Policy Settings.
