Not the way you want... A request on ip:443 is always going to land initially in the first
VH. This means the HTTPS session must be established using the cert from VH1. If the hostname
in the request is for site 2 or 3, this will then cause a browser alert.

Once the HTTPS session is up, you could then redirect to the port-based SSL VHs and start
a new session. Something like this:

<VH1 *:443>
  ServerName one
  ... real site one

<VH2 *:443>
  ServerName two
  Redirect / https://two:444/

<VH3 *:444>
  ServerName two
  ... real site two

How it works:

- request two:443, lands in first VH, browser alert (one != two)
- HTTPS session starts using cert from VH1
- apache reads Host header, switches to VH2
- VH2 redirects to two:444, browser re-requests to two:444
- request lands in VH3, new HTTPS session using correct cert, no alert (two == two).

Messy, and not much better than just putting all VHs on 443 and using the same cert for each
(ie, you get a browser alert and lose authentication).
