Ubuntu – Apache 2.2 Virtual Host on Ubuntu

I'm new to Linux world and I'm getting stuck with the Apache version 2.2 Virtual host configuration.

In my local /var/www I have 2 sites (and the default localhost) in their respective directories:

/var/www/importer
/var/www/foostore

Importer is an importer for a Opencart installed into daxstore directory, which I'm developing. I want two distinct sites working so I've copied the file

/etc/apache2/sites-available/default

into the same directory two times, renaming it into "importer" and "foostore" and then edited them to:

<VirtualHost importer:80>
ServerAdmin webmaster@localhost

ServerName  importer
DocumentRoot /var/www/importer/
<Directory />
    Options FollowSymLinks
    AllowOverride None
</Directory>
<Directory /var/www/importer>
    Options Indexes FollowSymLinks MultiViews
    AllowOverride None
    Order allow,deny
    allow from all
</Directory>
ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
<Directory "/usr/lib/cgi-bin">
    AllowOverride None
    Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
    Order allow,deny
    Allow from all
</Directory>
ErrorLog ${APACHE_LOG_DIR}/error.log
# Possible values include: debug, info, notice, warn, error, crit,
# alert, emerg.
LogLevel debug
CustomLog ${APACHE_LOG_DIR}/access.log combined
Alias /doc/ "/usr/share/doc/"
<Directory "/usr/share/doc/">
    Options Indexes MultiViews FollowSymLinks
    AllowOverride None
    Order deny,allow
    Deny from all
    Allow from 127.0.0.0/255.0.0.0 ::1/128
</Directory>

switching the name for the other side. I then edited /etc/hosts as follows:

127.0.0.1   localhost
127.0.1.1   VirtualHD
127.0.0.1   foostore
127.0.0.1   importer

Then I give the commands:

sudo a2ensite importer
sudo a2ensite foostore
sudo service apache2 restart

and apache goes right. When I try to access both sites, the browser redirect me on the foostore site (which also can't find some files but this is a matter for another question).
Where am I wrong?

Thank you sirs.
