[stunnel-users] Many services on the same port (VirtualHost)

Hello all!

Does anyone knows a way to make many services listening on the same port? I've got one stunnel4 server which allows me to crypt two http servers. The first service bind on port 465 and the second on 470. What I will is to let user access on the port 465 using 2 different ServerNames.

Thank you in anticipation, and excuse me for my quite bad english =D
