title: Can ELB redirect request depending on the URL?
body: <p>I am trying to set up my application server behind the Amazon Elastic Load Balancer. I am thinking to have one server dedicated for old version, and all other server dedicated for new version. I am thinking to implement this using version id in path parameter
  <p>e.g.
  <p>Current Version (3.0) : <a href="http://example.com/APPNAME/service" rel="noreferrer">http://example.com/APPNAME/service</a>
  <p>Old Version (2.2) : <a href="http://example.com/APPNAME/v2.2/service" rel="noreferrer">http://example.com/APPNAME/v2.2/service</a></p>
  
  <p>I would like to know:</p>
  
  <ol>
  <li>Does ELB has ability to look into HTTP request?</li>
  <li>Can ELB redirect request depending on the URL Path Parameter?</li>
  </ol>
