Cooperative Session-Based Filtering

A system comprising:

• one or more processors;
• and
• one or more computer-readable media having stored thereon computer-executable instructions that are executable by the one or more processors to implement a content distribution service configured to perform acts including:
• establishing a content distribution session with a client;
• passing through content from a content distribution service at a server-side to the client at a client-side over a network without filtering at the server-side;
• obtaining feedback in the form of filter state data communicated during the content distribution session from the client to the content distribution service, the filter state data indicating filtering criteria applied during the content distribution session by the client to filter content at the client-side;
• dynamically creating a session-based list for use by the content distribution service during the session based on the feedback from the client that incorporates the filtering criteria applied at the client-side, wherein the content distribution service is configured to create different session-based lists on demand for individual sessions with clients that are discarded at the conclusion of the individual sessions to avoid persistent storage of filter criteria for the clients by the content distribution service at the server-side;
• using the session-based list for a duration of the content distribution session to filter the content on the server-side using the filtering criteria applied at the client-side;
• and
• discarding the session-based list when the content distribution session concludes.

One or more computer-readable storage media storing instructions, that when executed by a computing device, cause the computing device to implement a content distribution service configured to perform acts comprising:

• establishing a content distribution session with a client;
• passing through content from a content distribution service at a server-side to the client at a client-side over a network without filtering at the server-side;
• obtaining feedback in the form of filter state data communicated during the content distribution session from the client to the content distribution service, the filter state data indicating filtering criteria applied during the content distribution session by the client to filter content at the client-side;
• dynamically creating a session-based list for use by the content distribution service during the session based on the feedback from the client that incorporates the filtering criteria applied at the client-side, wherein the content distribution service is configured to create different session-based lists on demand for individual sessions with clients that are discarded at the conclusion of the individual sessions to avoid persistent storage of filter criteria for the clients by the content distribution service at the server-side;
• using the session-based list for a duration of the content distribution session to filter the content on the server-side using the filtering criteria applied at the client-side;
• and
• discarding the session-based list when the content distribution session concludes.
