However, the fact that it supports PHP 4.2 and MySQL 3.23 makes me wonder how old the code base is! Makes me think it's using so many obsolete PHP methods, the deprecated MySQL extension, and is all procedural code (which almost always seems to be spaghetti code with PHP).
Server Name Indication (http://en.wikipedia.org/wiki/Server_Name_Indication) works around this by sending the host name during the TLS handshake, so that multiple domains can use SSL on the same IP address. In this case, only the host name is sent in the clear. The whole HTTP request and response are still encrypted.
