Thank you for mentioning, I totally forgot about it since IBM HTTP Server is currently only available for Windows servers and we are using Linux here.

I guess it may be possible to set up a similar configuration (with reverse proxy using something like Apache or nginx) on Linux.

But what I really would like to see is IBM to fix and update Domino's TLS/SSL features instead of recommending us the usage of additional software only available for one OS.

I totally agree and IBM HTTP Server for Domino is also only available as a 32bit application!!!
