title: Setting up wildcard domains on local host (OS X 10.5)?
body: <p>I am starting to develop a site which basically acts as WordPress MU, in the sense that a user can signup and have their own blog. I will be coding this in Rails, however I am hoping to be able to utilize wildcard subdomains, so I can use the format such as blog.example.com. I've done some searching but I can't find any good resources.</p>
  
  <p>Since I am using Rails, I'm not sure where to put this, as I am using Mongrel, and not Apache. I can bypass doing this on my local machine by developing remotely on my server, however I would only like to keep this as a last resort.</p>
  
  <p>I can give more details about my development environment if needed, but here are the basics:</p>
  
  <ul>
  <li>Mac OS X Leopard 10.5.6</li>
  <li>Ruby 1.8.7</li>
  <li>Rails 2.3.2</li>
  </ul>
