title: Connect Subdomain to Subsystem in FW1
body: <p>I have set up a subsystem in my app:</p>
  
  <pre><code>example.com/index.cfm/subsys:foo/bar
  </code></pre>
  
  <p>What I want to do is map a subdomain to that subsystem to eliminate the need for the subsystem specification in the PATH</p>
  
  <pre><code>subsys.example.com/index.cfm/foo/bar
  </code></pre>
  
  <p>We serve our FW1 app through IIS6 currently, but may migrate to Apache, so a solution in either is acceptable.</p>
