# Virtual hosts Include conf/extra/httpd-vhosts.conf
Modify httpd-vhosts.conf file
Add the following to your httpd-vhosts.conf file. Replace the internal domain name with yours.
NameVirtualHost 127.0.0.1
# Default virtual host that will bring up the WampServer home page <VirtualHost 127.0.0.1> ServerName localhost DocumentRoot "c:\wamp\www" </VirtualHost>
