# sessions directory and contents needs to be writeable by apache user during cron report generation with charts, so make raj member of www-data group:
	sudo usermod -a -G www-data raj
# set group to apache user for sessions dir:
	sudo chgrp -R www-data ./sessions
# set permissions so new files have apache user group (setgid):
	sudo chmod 2770 ./sessions
# make cgisession.id writeable by apache user:
	chmod 660 ./sessions/cgisession.id
