How to redirect or move a context

Warning2.png
Jetty 7 and Jetty 8 are now EOL (End of Life)

All development and stable releases are being performed with Jetty 9.
This wiki is now officially out of date and all content has been moved to the Jetty Documentation Hub

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>
