The present invention relates to a method for optimizing the use of client capacity when providing information contents to a user. First, two modes of navigation of the client are defined: a first, continuous navigation mode, characterized by restricted movement among the contents, and a second, discontinuous mode, characterized by unrestricted movement among the contents. Then it is determined which mode of navigation the user is currently using, and the utilization of client capacity is adapted based on the currently used mode of navigation. In the first mode of navigation, user action can be more easily anticipated, and the client capacity can be used for improving the ongoing media consumption. In the second mode of navigation, user action is more difficult to predict, and client capacity may be needed for handling unexpected actions.
