With the session pre-launch feature, a Horizon administrator can configure a published application so that the session starts before a user opens the application in Horizon Client. The session pre-launch feature enables faster start times for frequently used published applications.
You can enable the session pre-launch feature for a global application entitlement by enabling the pre-launch policy when you create or modify the global application entitlement. All the application pools in the global application entitlement must support the session pre-launch feature, and the pre-launch session timeout must be the same for all farms.
For information about configuring application pools and farms to use the session pre-launch feature, see the Setting Up Published Desktops and Applications in Horizon document.
The session pre-launch feature is not supported for remote desktops.
