Query a pool according to the hostname without opening the encryption

Hello   In an https connection the only thing that can be seen is the IP and hostname. How can I choose the pool to send a connection to depending on the hostname without opening the encryption?  ...

adding to Amine_Kadimi ,

most clients send intended server hostname during SSL session setup, so that SSL server can response with proper server's certificate.
this method allows same server serves mutiple SSL hostnames using different certificate for each hostname.
the sample config above actually reads that hostname.
