This paper discusses the possibility to perform a feedback control of a Web server's dynamic properties. The problem gets into account in a number of tasks related to the maintenance of one or multiple servers. In order to perform the research, an experiment is conducted. The server's working conditions are simulated by load testing, the controlling parameters are chosen, the approach is described to affect to the server's dynamics using these parameters. A mathematical model of the Web server is suggested in terms of DLTI systems. The results achieved in the course of the experiment are compared with theoretical considerations. Finally, the possibility of the experiment program automatization is discussed.
