I know this post is old, but I am looking at the same type of issue as
it relates to old browser versions we have to support. But apparently its
"As a rule, it is impossible to host more than one SSL virtual host on
the same IP address and port."
Taken from here
The only other way I can think of around this issue, is to create
separate vhosts, where the first one to negotiate will set insecure
protocols, do some detection using mod-rewrite - in my case old MS IE
versions - and then specify either an "Hey your browser is old, upgrade!"
page, or redirect to a more secure vhost with the correct config.
But I am still investigating and open to comments.
