Ok, you accidentally left out the /conf/ folder in the grep command, so here is the output of grep Include /etc/httpd/conf/httpd.conf
[root@solution ~]# grep Include /etc/httpd/conf/httpd.conf
# Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews
# Options MultiViews Indexes SymLinksIfOwnerMatch IncludesNoExec
# (You will also need to add "Includes" to the "Options" directive.)
AddOutputFilter Includes html
Will let you know about the wildcard *80 results soon. Would like to know your thoughts in the meantime on the grep output above.
