You can set up intermediate servers between your View servers and Horizon Client devices to perform tasks such as load balancing and off-loading SSL connections. Horizon Client devices connect over HTTPS to the intermediate servers, which pass on the connections to the external-facing View Connection Server instances or security servers.
To off-load SSL connections to an intermediate server, you must complete a few key tasks:
Import the SSL certificate that is used by the intermediate server to your external-facing View servers
Set the External URLs on your external-facing View servers to match the URL that clients can use to connect to the intermediate server
Allow HTTP connections between the intermediate server and the View servers
