Pat,

Get is a handshake at the very least.  One computer reaching out to
another and asking for information, its up the computer being asked what
'should' or 'should not' be returned to that user.

I suggest that it is not, and cannot possibly be, either of these. Or
indeed any other English paraphrase of some communication act between
human beings. GET is not a conversation, it is a mechanical transfer
protocol. We can of course speak metaphorically using this language,
just as we speak of machine "instructions" and software "agents" and so
on: our technical vocabulary is riddled with these suggestive usages.
But sometimes it is vitally important to remind ourselves that these
really are only suggestive metaphors. Computer hardware does not obey as
humans obey orders; software does not act as humans act; and GET does
not request, assert, claim or suggest in any human senses of these
words. It simply initiates a process which results in bytes being
transferred from one place to another on a network.
