A method and apparatus for content-based billing is provided. Techniques are provided for intercepting, modifying, and retransmitting a request between various entities engaged in content-based billing in the context of the World Wide Web. Various techniques such as HTTP proxy servers, wireless protocol gateways, routers, and level 41 switches may be used for intercepting the request. The request maybe modified based on numerous factors such as profile information, levels of service, and requested content. The entities that engage in content-based billing include but are not limited to users (including mobile users), content providers, access providers (including HTTP proxy servers).

A mechanism for managing data communications is provided. A circularly arranged set of buckets is disposed between input buffers and output buffers in a networked computer system. Connections among the system and clients are stored in the buckets. Each bucket in the set is successively examined, and each connection in the bucket is polled. During polling, the amount of information that has accumulated in a buffer associated with the connection since the last poll is determined. Based on the amount, a period value associated with the connection is adjusted. The connection is then stored in a different bucket that is generally identified by the sum of the current bucket number and the period value. Polling continues with the next connection and the next bucket. In this way, the elapsed time between successive polls of a connection automatically adjusts to the actual operating bandwidth or data communication speed of the connection.
