Hi, we are making a lot of webservice request with our sybase db version 11 but now we can not access a tls webservice which we could access a few days before. As i can see, the server has changed to sni-mode (Server Name Indication - https://en.wikipedia.org/wiki/Server_Name_Indication), so i have to use the sni extension server_name to proceed working with this webservice. But i can not see any examples to use this with sybase 11, 16 or the newest version 17. In the documentation there is also no hint for this.

All current popular browsers can work with this but what about sybase db? Is it possible to use the sni extension "server_name" and if it so, how can i use this with my sybase webservice function?

Best regards and thanks for your help, Christian

A late reply:

According to a comment by Tim McClements, SNI is supported as of 17.0.10:

One thing that has changed recently is Server Name Indication is now used for the handshake. This sends the expected hostname to the server so it can return the matching certificate. [...] That could explain why only 17.0.10 works.
