NameVirtualHost directive warning for Localhost - apache

Question

I have read through many posts and have configured WAMP for 2 sites on the same IP address as follows (httpd.conf extract):
#Tell Apache to identify which site by name
NameVirtualHost *:80
#Tell Apache to serve the default WAMP server page to "localhost"
<VirtualHost 127.0.0.1>
ServerName localhost
DocumentRoot "C:/wamp/www"
</VirtualHost>
#Tell Apache configuration for 1 site
<VirtualHost 127.0.0.1>
ServerName client1.localhost
DocumentRoot "C:/wamp/www_client1"
<Directory "C:/wamp/www_client1">
allow from all
order allow,deny
AllowOverride all
</Directory>
DirectoryIndex index.html index.php
</VirtualHost>
#Tell Apache configuration for 2 site
<VirtualHost 127.0.0.1>
ServerName client2.localhost
DocumentRoot "C:/wamp/www_client2"
<Directory "C:/wamp/www_client2">
allow from all
order allow,deny
AllowOverride all
</Directory>
I have also changed the Windows hosts file to add 127.0.0.1 client1.localhost etc. however when I restart the WAMP services, //client1.localhost and //client2.localhost go to the default site in the c:\wamp\www folder.
Any help really appreciated.

Answer 1

Have you included your vhosts.conf in your httpd.conf?
Uncomment this line (the one that starts with 'Include') near the bottom of httpd.conf:
# Virtual hosts - leave this commented
Include conf/extra/httpd-vhosts.conf
Edit:
It looks like the problem is that NameVirtualHost and VirtualHost have to match, so you can't have NameVirtualHost *:80 and VirtualHost 127.0.0.1. Instead, use NameVirtualHost *:80 and VirtualHost *:80 or NameVirtualHost 127.0.0.1:80 and VirtualHost 127.0.0.1.
If they don't match, you will see the behavior mentioned in your comment where either the virtual host that doesn't match the others will get hit, or if they are all the same, the first on (your default localhost) will get hit.

Try this configuration, its just a few minor mods to yours
#
# Use name-based virtual hosting.
#
NameVirtualHost *:80
## must be first so the the wamp menu page loads
<VirtualHost *:80>
ServerAdmin webmaster#homemail.net
DocumentRoot "C:/wamp/www"
ServerName localhost
ServerAlias localhost
<Directory "C:/wamp/www">
Order Deny,Allow
Deny from all
Allow from 127.0.0.1
</Directory>
</VirtualHost>
#Tell Apache configuration for 1 site
<VirtualHost *:80>
ServerName client1.localhost
DocumentRoot "C:/wamp/www_client1"
<Directory "C:/wamp/www_client1">
AllowOverride All
order Allow,Deny
Allow from all
</Directory>
DirectoryIndex index.html index.php
</VirtualHost>
#Tell Apache configuration for 2 site
<VirtualHost *:80>
ServerName client2.localhost
DocumentRoot "C:/wamp/www_client2"
<Directory "C:/wamp/www_client2">
AllowOverride All
order Allow,Deny
Allow from all
</Directory>
