# run_mode: controls in which mode the vhost should be run, there are different setups
#           possible:
#   - normal: (*default*) run vhost with the current active worker (default: prefork) don't
#             setup anything special
#   - itk: run vhost with the mpm_itk module (Incompatibility: cannot be used in combination
#          with 'proxy-itk' & 'static-itk' mode)
#   - proxy-itk: run vhost with a dual prefork/itk setup, where prefork just proxies all the
#                requests for the itk setup, that listens only on the loobpack device.
#                (Incompatibility: cannot be used in combination with the itk setup.)
#   - static-itk: run vhost with a dual prefork/itk setup, where prefork serves all the static
#                 content and proxies the dynamic calls to the itk setup, that listens only on
#                 the loobpack device (Incompatibility: cannot be used in combination with
#                 'itk' mode)
#
# run_uid: the uid the vhost should run as with the itk module
# run_gid: the gid the vhost should run as with the itk module
#
# mod_security: Whether we use mod_security or not (will include mod_security module)
#    - false: don't activate mod_security
#    - true: (*default*) activate mod_security
#
# logmode:
#   - default: Do normal logging to CustomLog and ErrorLog
#   - nologs: Send every logging to /dev/null
#   - anonym: Don't log ips for CustomLog, send ErrorLog to /dev/null
#   - semianonym: Don't log ips for CustomLog, log normal ErrorLog
