Hi, I've made some changes in my ispconfig.vhost file to get a server through pci compliance and get a higher rating on Qualys's SSL server tests. but I can't find any template file for this vhost config on the server, only the apache_ispconfig.vhost.master file in ispconfig3_install/install/tpl that comes with the installation/update archive. can this file be copied to the conf-custom folder and modified there? if not, is there any way to preserve the changes to this vhost file on updates? (i'm assuming it will get replaced on any update), or do I need to either remember to change the template file in each update package before applying the update, or re-apply the changes to the vhost file after each update?
