currently, html is belonging to root group/owner and httpd is running 
under apache user/group.

what should i change html to, so that httpd can run safely under apache 
user/group???

or should i change httpd to run under a different user/group???

if i keep httpd running on apache user/group, should i change html to 
apache group/owner???

thank you for all your help.
