The /var directory is for "Adminsitive files, such as log files, used by
various utilities" (Running Linux O'Reilly) that also means things like
print jobs, mail, system accounting...

Becuase logs are (normally) in /var/ and can expand unpredictably I'd
suggest that you may want to think about moving the web directory over to
/home/ but I don't really know anything in particular about Red hat which
may have specific requirements, (though I doubt it). IIRC I think openBSD
has it's apache in /var/... so it's not unusual.

Anyway, seeing as you look like you are using apache, you may be able to
just change the httpd.conf DocumentRoot to /home/www/ which would be fairly
easy, or perhaps you could make a sym link? Either for the www folder or for
the logs.

Do you mean a non destructive repartition? I don't think so under Linux...

If you mean a href link, <a href="/home/files">here then no, they won't be
accessible.

Kind regards,
