Why does apache give me this error message in my logs? Is it a false positive?
[warn] Init: Name-based SSL virtual hosts only work for clients with TLS server name indication support (RFC 4366)
I have recently upgraded from Centos 5.7 to 6.3, and by that to a newer httpd version. I have always made my ssl virtualhost configurations like below. Where all domains that share the same certificate (mostly/always wildcard certs) share the same ip. But never got this error message before (or have I, maybe I haven't looked to enough in my logs?) From what I have learned this should work without SNI (Server Name Indication)
Here is relevant parts of my httpd.conf file. Without this VirtualHost I don't get the error message.
NameVirtualHost 10.101.0.135:443
