title: How to change the BaseUrl on a Hudson behind a Proxy?
body: <p>How can i change the BaseUrl on a Hudson behind a Proxy?</p>
  
  <p>I'm running a Hudson installation behind a proxy.
  The problem is, that any url (email, jabber, tray app) in the web application is set to the local proxy and not to the virtual host. How can i fix that, is there any environment variable? </p>
  
  <p>I have just found "Hudson Url" for email's, but thats all.</p>
  
  <pre><code>&lt;VirtualHost *:8080&gt;
      ProxyPass       / http://127.0.0.1:8070/
      ProxyPassReverse    / http://127.0.0.1:8070/
      ProxyRequests       Off
  
      &lt;Proxy http://127.0.0.1:8070/*&gt;
          Order deny,allow
          Allow from all
      &lt;/Proxy&gt;
  &lt;/VirtualHost&gt;
  </code></pre>
