Name for HTTP Request+Response

问题

There's one thing I haven't found in rfc 2616 and that's a "canonical" name for a request/response pair. Is there such thing?

  4.1 Message Types

    HTTP messages consist of requests from client to server and responses
    from server to client.

       HTTP-message   = Request | Response     ; HTTP/1.1 messages

Taking this as a template, which word would you put in the following sentence?

  A single complete HTTP ... consists of one HTTP Request and one HTTP Response

       HTTP-... = Request Response

roundtrip? cycle?

回答1:

The spec calls them "exchanges" (or "request/response exchanges"),

In HTTP/1.0, most implementations used a new connection for each
request/response exchange. In HTTP/1.1, a connection may be used for one or more request/response exchanges.

回答2:

Exchanges is nice name, also we can use Connection, Communication or session

回答3:

_{(answer originally taken from a duplicate question)}

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.

回答4:

Transaction, yes, or "A singe HTTP Request consists of one HTTP Request message and one HTTP Response message."
