Root folder is /usr/htdocs instead of /var/www/localhost/htd

[joedestroyer]

Would anyone know why my /var/www/localhost/htdocs folder is not longer used and instead apache is using /usr/htdocs?
I am using apache 2.2.22
My configuration for default_vhost.include is as follow


DocumentRoot "/var/www/localhost/htdocs"

# This should be changed to whatever you set DocumentRoot to.
<Directory "/var/www/localhost/htdocs">
# Possible values for the Options directive are "None", "All",
# or any combination of:
# Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews
#
# Note that "MultiViews" must be named *explicitly* --- "Options All"
# doesn't give it to you.
#
# The Options directive is both complicated and important. Please see
# http://httpd.apache.org/docs/2.2/mod/core.html#options
# for more information.
Options Indexes FollowSymLinks

# AllowOverride controls what directives may be placed in .htaccess files.
# It can be "All", "None", or any combination of the keywords:
# Options FileInfo AuthConfig Limit
AllowOverride All

# Controls who can get stuff from this server.
Order allow,deny
Allow from all
</Directory>
