Method for operating a cache arranged along a transmission path between client terminals and at least one server, and corresponding cache

摘要

First type cache (DANE) arranged along a transmission path between a client terminal and at least one server, which:
- is configured to receive, from the client terminal, a request for a first representation of a segment of a multimedia content, said multimedia content being available at several representations,
- and comprises a module (2) configured to send a response to the client terminal which comprises:
–  one alternative representation of said segment, which is cached by said first type cache (DANE);
–  first additional information preventing a second type cache - arranged between the first type cache (DANE) and the client terminal - from caching the alternative representation of said response; and
–  second additional information identifying the alternative representation of said response.
