Citrix products deliver applications across networks. Applications reside on the Citrix server or remote machines belonging to the server; access to those applications is delivered to the Citrix clients via Citrix's ICA protocol. ICA supports a full GUI interface of the server application on the client side.
VuGen records GUI activity on the Citrix client and replays it to the Citrix server.
