Off-load SSL Connections to Intermediate Servers
Horizon Client must use HTTPS to connect to View. If your Horizon clients connect to load balancers or
other intermediate servers that pass on the connections to View Connection Server instances or security
servers, you can off-load SSL to the intermediate servers.
Import SSL Off-loading Servers' Certificates to View Servers
If you off-load SSL connections to an intermediate server, you must import the intermediate server's
certificate onto the View Connection Server instances or security servers that connect to the intermediate
server. The same SSL server certificate must reside on both the off-loading intermediate server and each off-
loaded View server that connects to the intermediate server.
If you deploy security servers, the intermediate server and the security servers that connect to it must have
the same SSL certificate. You do not have to install the same SSL certificate on View Connection Server
instances that are paired to the security servers and do not connect directly to the intermediate server.
If you do not deploy security servers, or if you have a mixed network environment with some security
servers and some external-facing View Connection Server instances, the intermediate server and any View
Connection Server instances that connect to it must have the same SSL certificate.
If the intermediate server's certificate is not installed on the View Connection Server instance or security
server, clients cannot validate their connections to View. In this situation, the certificate thumbprint sent by
the View server does not match the certificate on the intermediate server to which Horizon Client connects.
Do not confuse load balancing with SSL off-loading. The preceding requirement applies to any device that is
configured to provide SSL off-loading, including some types of load balancers. However, pure load
balancing does not require copying of certificates between devices.
For information about importing certificates to View servers, see "Import a Signed Server Certificate into a
Windows Certificate Store" in the View Installation document.
Set View Server External URLs to Point Clients to SSL Off-loading Servers
If SSL is off-loaded to an intermediate server and Horizon Client devices use the secure tunnel to connect to
View, you must set the secure tunnel external URL to an address that clients can use to access the
intermediate server.
You configure the external URL settings on the View Connection Server instance or security server that
connects to the intermediate server.
If you deploy security servers, external URLs are required for the security servers but not for the View
Connection Server instances that are paired with the security servers.
