setup multiple SSL servers in one config

[Jonathan Garvin]

I'm in the process of trying to convert a Pound config file that manages
multiple SSL sites over to Nginx.  If I just have one site setup in the
nginx.conf file then everything, including the SSL, works fine. But if I
add a second server block for a different domain, then the second tries
to use the SSL certificate for the first, resulting in the browser
raising security warnings.  My conf file is below.  Any hints at what I
am doing wrong would be greatly appreciated.
