Proxies

• A proxy server is an intermediary piece of hardware / software sitting between client and backend server.
  • Filter requests
  • Log requests
  • Transform requests (encryption, compression, etc)
  • Cache
  • Batch requests
    • Collapsed forwarding: enable multiple client requests for the same URI to be processed as one request to the backend server
    • Collapse requests for data that is spatially close together in the storage to minimize the reads
