Hi Yutaka, I think it’s better for this question to be another topic though it’s related with my last question (how to implement SNI on https) which has been answered already, thanks again here. Since the limited browsers support SNI, can I ask your another question? If we'd still like to achieve the same scenario without using SNI: most customers still https access the portal via our delegate FQDN (i.e. https://portal.abc.com/) with its certificate file, and a couples of customers would like to https access our portal via their own domain name ( https://portal.xyz.com/), but with their own ssl cerfiticate, rather than prompting the certificate dismatching the hostname. How can we achieve it with on the same delegate host with multiple ssl certificates without using SNI? If possible, then we prefer to this solution, insteadof SNI, which requires too much. Could you please tell me the details? Thanks a lot. Regards, David
