Do I have to duplicate the Virtualhost directives for port 80 and 443?

Can’t you use an include directive to include the common rules. here

article

eg.:

<VirtualHost _default_:80>
    ...
    include conf/common_rule.conf
</VirtualHost>

<VirtualHost _default_:*>
    ...
    include conf/common_rule.conf
</VirtualHost> 

<VirtualHost _default_:443>
    ... #SSL rules
    include conf/common_rule.conf
</VirtualHost>
