Dear all, I am struggling with a SetEnvIf Directive and ipv6: <If "-R fe80::216:3eff:feaf:525b/64"> SetEnvIf showindex=1 </If> Error message: Cannot parse condition clause: syntax error, unexpected ':', expecting $end: -ipmatch requires subnet/netmask as constant argument It seems that ipmatch cannot handle ipv6 adresses? Is this true?
