Abstract

A method, system, and computer-readable code with which environmental factors can be used to dynamically filter the content being delivered from a server to a user'"'"'s workstation. A rule-based approach is used to select an appropriate filter, enabling varying types and degrees of content reduction to be applied based on currently-existing conditions. This provides a way to manage the volume of data received by the user, without requiring input from the user, by reducing the amount of data sent to him by a server. In the preferred embodiment, conditions to be monitored include billing information related to the user'"'"'s account with his connection service provider; characteristics of the device he is currently using, including its available storage capacity; and/or behavioral characteristics of this user when he requests to download files.
