What is a request-response pair called? [duplicate]

  • RFC2616 calls it an Exchange.
  • Wireshark and HTTPNetworkSniffer call it a Request/Response.
  • Fiddler calls it a Session.
  • Charles calls it a Sequence.
  • HTTP Scoop calls it a Conversation.
  • Other vocabulary includes: Message, Transaction, Communication.

I would go for Exchange or RequestResponse.

I also went to name it Operation in my code as I would queue Operations, flush Operations, pause or resume Operations.
