I believe that the different port idea is correct (for any web server - 
not just tomcat). 

Another point to consider is that if tomcat is used in conjunction with a 
web server (such as apache or IIS), the web server does all of the SSL 
stuff for the communication with the browser, so you are stuck with web 
server limitations that are out of tomcat's control.

Sure, what we're working with is possibly using different server
certificates for different servlets, is this at all possible? From what I
can tell right now, no.

Basically what I see right now is if we turn on ssl support it uses the
certificate that you specify for each connection from the
SSLServerSocketFactory.  The only way I can see doing this is to specify a
different port for different certificates, correct?
