title: How can I specify a second "site URL" in my facebook application to support localhost development?
body: <p>I have a Facebook login on my site currently working on my development environment.  The "site URL" I have specified in the Facebook application settings is :</p>
  
  <pre><code>http://127.0.0.1.
  </code></pre>
  
  <p>I am about to roll this out to production and will change the "site URL" to "<a href="http://mysite.com" rel="nofollow">http://mysite.com</a>", however this will cause my development setup not to be able to login to Facebook.  I suppose I could create a second facebook application.  I have seen this question asked in slightly different ways but with no definitive answer.</p>
