title: Symfony dynamic subdomains
body: <p>I'm trying to match subdomains to a customer id in symfony.</p>
  
  <p>i.e. i have customer1.example.com and customer2.example.com</p>
  
  <p>Domains are stored in a table.</p>
  
  <p>When a user goes to customer1.example.com, I would like to get the subdomain, look up the domain name in the database, once matched, it will then deploy the app config for that customer and then store the customer_Id in a global  attribute so i know exactly which customer I'm dealing with througout the whole application. The virtual host will have the relevant wildcard servername.</p>
  
  <p>Have you managed to achieve this, and if so, how? If not, any ideas would be a great help! </p>
  
  <p>I'm thinking about using a filter to do it.</p>
