I followed the CBAND tutorial and with some personal modifications it works perfectly for HTTP websites. BUT not with HTTPS with SSL! Somehow ispconfig uses a different config file than vhost.conf.master, because the HTTP_INCLUDE, which I moved after the variable "ServerName", is ABOVE the variable in the HTTPS section??? Cband errors when starting Apache 2 is the result. (undefined virtual hostname) So who knows how to solve this ?
