Zorp Professional 7 supports the Server Name Indication (SNI) TLS extension, as described in RFC 6066. You can configure a mapping between hostnames and certificates, and if the peer sends an SNI request, Zorp automatically selects the matching certificate to show to the peer. For details, see Section 5.5.18, Class SNIBasedCertificate in Zorp Professional 7 Reference Guide and Procedure 4.1, Configuring Server Name Indication (SNI) in How to configure HTTPS proxying in Zorp 7.
