title: Is there an easy way to get the ServerName in Symfony?
body: <p>I have been searching for an easy way to get the ServerName of the machine where Symfony runs in Symfony (so that my app adapts when it is used on a host with a different ServerName), but I couldn't find one. I created a variable in app.yml and I fetch it, but I still wonder if there is no easier way to do this.
  How are you doing this? I'm using Symfony 1.2 and 1.4 on different projects.</p>
