title: How can i change the contextpath of jenkins?
body: <p>We have a situation trying to run jenkins behind apache,</p>
  
  <p>we need to specify a new context path because we already have an instance of jenkins in ./Jenkins, so we try to use the parameter --prefix=/jenkins2/ in order to have the 2 instances separated.</p>
  
  <p>The problem is that with that parameter, when i hit the url <a href="http://myserver.com/jenkins2" rel="nofollow noreferrer">http://myserver.com/jenkins2</a> i have this:</p>
  
  <p><strong>HTTP ERROR 404</strong></p>
  
  <p>Problem accessing /. Reason:
      Not Found</p>
  
  <p>Powered by Jetty:// 9.4.z-SNAPSHOT</p>
  
  <p>any help?</p>
