again: this is bad advice, httpd is runing as user apache so you should 
avoid giving that user write access to stuff in /var/www/ unless it 
needs to (CGI, file uploads, etc...).
The apache user only needs read access. The users editing the content 
need write access.
Make /var/www/* owned by root, or yourself, or some brand new account, 
but not by apache. Then use groups and sgid bits to give write access 
(to relevant subdirs) to whoever needs to edit the content.
