I want to install mod_python under our ISPConfig. Surely this is not a problem, but I have a question regarding the configuring. As ISPConfig does not support mod_python out of the box, I have to edit the vhosts file myself to add the nessecary lines. This is not a problem at all. My question is: When I add those lines, and after a week or two want to edit that VHost under ISPConfig, will those lines be deleted or preserved?
