# Note:
# www/apache24 build changed from static MPM to modular MPM loading!
#
# This file was installed as fall back, since no activated MPM
# was detected in the existing httpd.conf.
#
# Please merge additions from httpd.conf.sample into your httpd.conf!
#
# After activating one of the mpm_modules in httpd.conf it is save
# to deactivate the "LoadModule" line in this file.
#
# In case mod_(php|perl|python|...) modules from the official FreeBSD
# package repo are installed please use the mpm_prefork module, else
# feel free to test mpm_event (preferred) or mpm_worker.

# For more information see:
