How did you create the vhosts?

It's a XAMPP installation I created the appropriate vhosts within the apache-vhost-configuration file.

here's an example of a VHost:

<VirtualHost *:80>
    ServerAdmin admin@local
    DocumentRoot "/Users/cbuchler/Development/web.dev/public/"
    <Directory "/Users/cbuchler/Development/web.dev/public">
      Options Indexes FollowSymLinks Includes ExecCGI
      AllowOverride All
      Require all granted
    </Directory>
    ServerName web.dev
    ServerAlias www.web.dev
    ErrorLog "logs/web-dev-error_log"
    CustomLog "logs/web-dev-custom-log" common
</VirtualHost>

Hi,

I use the following technique to create my Virtual Hosts, hope it helps you:

#First I leave reserved the localhost for get access into my www folder
<VirtualHost localhost:80>
 ServerName localhost
 DocumentRoot "c:/wamp/www/"
</VirtualHost>

#myapp.dev VirtualHost
<VirtualHost myapp.dev:80>
 ServerName myapp.dev
 DocumentRoot "c:/wamp/www/myapp/public"
</VirtualHost>

#subdomain.myapp.dev VirtualHost
<VirtualHost subdomain.myapp.dev:80>
 ServerName subdomain.myapp.dev
 DocumentRoot "c:/wamp/www/subdomain_app/public"
</VirtualHost>

Later I use the hosts file in my windows OS to enable it.

We do have the same setup with the only difference that my vhosts are not directly tied to a specific IP-Address.
