Apache HTTPS Configuration on CentOS
Perform the configuration exactly as described in Centos HOWTO.
IMPORTANT Notes:
* Use wildcard to define CN (Common Name) at generating CSR, to match all servers used in virtual hosting. Only 1 certificate can be used in 1 apache instance. E.g.: the common name *.softxs.ch will match with met.softxs.ch, linthal.softxs.ch, etc.
* Use full hostname in the header of the VirtualHost section intead of '.*:443'
* Use 'Options -Indexes' in the VirtualHost section.
