Hi,
> !!! I DO NOT want to use virtual domains as the management
You are free to not want to use the VirtualHost, but then, do not come complaining that it does not work.
All your hosters uses the VirtualHost.
The only way that relative links work on your websites AND locally is to use the VirtualHost. Full stop.
Read carefully :
