Installing symfony - setting up the virtual host 2

Just a quick clarification on my previous post about setting up virtual hosts, which seems to be a little misleading.

You do also need to define your localhost as follows:

<VirtualHost *:80>
  ServerName localhost
  DocumentRoot "/path/to/www"
  DirectoryIndex index.php
</VirtualHost>

(localhost should already be defined in your hosts configuration file).
This way you can still access all your other applications.

Thoughts?
