The document outlines the application enumeration and launch processes when using a Citrix environment. The application enumeration process involves a user authenticating through a web interface, which uses their credentials and SIDs to retrieve a list of available applications from the local host cache. The selected application data is then passed back to the interface. The application launch process determines the least loaded server that has the selected application installed, obtains its IP address, and uses an ICA file to launch the application session on that server for the user.
