FYI you can do transparent proxies for HTTP - but not HTTPS. That would
be called a "man-in-the-middle" attack, and SSL by design resists such
fiddling.

If your intent is to "know" what URLs your internal staff are
downloading from HTTPS servers, then I think you won't find an easy
answer. Only a terminating proxy will achieve what you want - and then
that's dependent on how the client is configured.
