The https interception guide in this link:

I agree. That page should not use the word "intercept" when talking about HTTP CONNECT inspection and bumping -- CONNECT requests are not (normally) intercepted. Pull requests improving documentation welcome!

Both directives support SslBump, but each works with a different kind of traffic.

    This http_port is for plain text HTTP interception. The configuration
    needs an https_port (note the "s") dedicated to TLS interception
    instead.

    The above rule should redirect traffic to that https_port.
