Then there is no active request at this time except for your cachemgr
request.

Confirms this. all open connections are idle and no data is being
exchanged.

Correct, as there is no such correlation.

The client<->squid and squid<->server connections are independent of
each other and both are idle waiting for the next request to happen.

The first request from any client for a object on this server will use
the currently idle server connection. And the client will use his
idle connection for the next request regardless of which server this
request is for.

For a history of what clients have already exchanged data with what
servers see access.log. In the scope of the question cachemgr should
only be used for identifying the requests currently being processed,
not requests which have already been completed.
