Sure, but what has this to do with redirection? That happens with or
without redirections being followed.

What you describe is the persistent connection cache, which is only used
when prsistent/keepalive connections are enabled.

You keep changing your problem, or what you describe as your problem. That
makes it a bit hard to help you.

If you need to control how tcp connections are made per subrequest,
and you need to use persistency, then you indeed need to implement
redirections on your own OR you need to implement persistency on your own.
