title: Is there away to use SetEnvIf with host and ip address?
body: <p>I'm using setenvif like so:</p>
  
  <pre><code>SetEnvIf Host ^dev\.mydomain\.com$ FLOW_CONTEXT=Development
  SetEnvIf Host ^(www\.)?mydomain\.com$ FLOW_CONTEXT=Production
  </code></pre>
  
  <p>What I want to know is, can I also somehow restrict dev.mydomain.com to an IP address? So that the world and his dog can't see my site in Development context?</p>
