How to redirect or move a context

Jetty 7 and Jetty 8 are now EOL (End of Life)

THIS IS NOT THE DOCUMENTATION YOU ARE LOOKING FOR!!!!!

All development and stable releases are being performed with Jetty 9 and Jetty 10.

This wiki is now officially out of date and all content has been moved to the Jetty Documentation Hub

Direct Link to updated documentation: http://www.eclipse.org/jetty/documentation/current/moved-context-handler.html

You can use the MovedContextHandler to relocate or redirect a context that has changed context path and/or virtual hosts.

You can configure it to permanently redirect the old URL to the new URL, in which case Jetty sends a Http Status code of 301 to the browser with the new URL. Alternatively, you can make it non-permanent, in which case Jetty sends a 302 Http Status code along with the new URL.

In addition, as with any other context, you can configure a list of virtual hosts, meaning that this context responds only to requests to one of the listed host names.

Suppose you have a context deployed at /foo, but that now you want to deploy at the root context / instead.

First you reconfigure and redeploy the context on Jetty.
Next you need a way to redirect all the browsers who have bookmarked /foo to the new path. You create a new context xml file in $JETTY_HOME/contexts and configure the MovedContextHandler to do the redirection from /foo to /.

Here's an example. This is a permanent redirection, which also preserves pathinfo and query strings on the redirect:

<?xml version="1.0"  encoding="ISO-8859-1"?>
<!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN" "http://www.eclipse.org/jetty/configure.dtd">

<Configure class="org.eclipse.jetty.server.handler.MovedContextHandler">
  <Set name="contextPath">/foo</Set>
  <Set name="newContextURL">/</Set>
  <Set name="permanent">true</Set>
  <Set name="discardPathInfo">false</Set>
  <Set name="discardQuery">false</Set>

  <Set name="virtualHosts">
    <Array type="String">
          <Item>209.235.245.73</Item>
          <Item>127.0.0.73</Item>
          <Item>acme.org</Item>
          <Item>www.acme.org</Item>
          <Item>server.acme.org</Item>
    </Array>
  </Set>

</Configure>
