Re: Re: Set SSLCipherSuite dependent on client IP

Are you sure that you have any MD5 ciphers enabled. Most of them are disabled nowadays. For example on my OSX I only have 1 MD5 available:

:~ $ openssl ciphers -v

Yes but to determine the context from which the <If> takes place
(VirtualHost, directory, location..), the server needs to know the
request header, thus negotiate TLS with the user-agent already.
Chicken and egg..
