Certificate issue on two IP-addresses with same port

[Martin Schöttler]

I need to run two web applications (Ruby on Rails)
on one server over SSL. Both applications shall run on port 443 (other 
wise we get firewall problems).

What I did:

- I got two IP-addresses (85.214.47.37, 85.214.56.139) for the server.
- I connected different domains to that addresses (gedis-intern.de -> 
85.214.47.37, gedis-second.de -> 85.214.56.139
- I configured two vhosts for nginx to listen on
   - listen 443; server_name secure.gedis-intern.de;
   - listen 443; server_name  secure.ticket-db.gedis-second.de;
- I provided certificates for the two vhosts (ssl_certificate, 
ssl_certificate_key)

When I connect to the second application 
(https://secure.ticket-db.gedis-second.de), then the *wrong certificate* 
is presented (that of the first one) to the client. Therefore the 
browser displays a warning, which confuses the user. (*That is the problem*)

If I set port 444 for the second application, than everything works 
fine. But - as I said - port 444 is sometimes blocked by firewalls.

Any help is appreciated!

Thanks,
Martin
