4.3 Hosted Cache with Block Hashes and Data Blocks

  • Article

This section presents an example of a hosted cache that has all the block hashes associated with the segment and all the data blocks.

In this sequence, on availability of new blocks for a segment, the client uses the protocol to offer the associated segment to the hosted cache. The hosted cache determines that it already has all blocks for the segment and responds with a code of zero.
