4.5 Hosted Cache with Data Blocks
This section presents an example of a version 2.0 hosted cache that has all the data blocks associated with all the segments in the list and a version 2.0 client.
In this sequence, upon the availability of new segments, the client uses this protocol to offer the associated segments to the hosted cache. The hosted cache determines that it already has all blocks for all the segments and responds with a code of 0.
