Abstract
Techniques for caching media data, including streaming media data, using content-sensitive identifiers. The content-sensitive identifiers enable a caching proxy or a caching server to unambiguously determine the version or contents of media data cached by the caching proxy for a particular data pointer or data reference (e.g., a URL) such that an appropriate version of the media data can be served to a requesting client system in an efficient and economical manner.
