Angel,
If you are trying to virtual host multiple domains with a single IP address over https, that's not possible. Here's a good explanation from the Pound website at http://www.apsis.ch/pound:

HTTPS does not allow virtual hosting
This is not a limitation of Pound, but of HTTPS - no Web server or proxy are able to do it due to the nature of the beast.
In order to see why this is the case we need to look at the way HTTPS works. Basically there are three stages in any HTTPS connection:
Connection negotiation - the client (your browser) and the server (Web server or proxy) negotiate the basic parameters: ciphers to use, session key, etc.
Connection authentication: at the very least the server presents the client with a certificate that says "I am server www.encrypted.com - and certificate.authority.org will verify that". The client may also present a certificate of its own at this stage.
Request/response cycle: normal HTTP is sent (through the encrypted channel) back and forth.
The vital point to notice here is that connection authentication takes place BEFORE any request was issued.
On the other hand, the way virtual hosting works is for the client to specify in the request to which server it would like to talk. This is accomplished via a Host header:
GET /index.html HTTP/1.1
Host: http://www.virthost.com
Combining the two we get to an impasse: on connection setup the server will reply with the certificate for "www.realhost.com", but the request is really for "www.virthost.com" - and most browsers will scream blue murder (as well they should) if the two do not match.
