post_virtualhost_global.conf does not exist

HI, I am trying to install xsendfile, but i dont understand this step: - Appended /etc/apache2/conf.d/includes/post_virtualhost_global.conf with XSendFilePath /home/[path]/public_html/ Do i need to open it in root like this? nano /etc/apache2/conf.d/includes/post_virtualhost_global.conf And add this line? XSendFilePath /home/[path]/public_html/ btw, i tried to run this, but there is no such file as post_virtualhost_global.conf: nano /etc/apache2/conf.d/includes/post_virtualhost_global.conf Thanks
