RedirectFilter

What is it?

RedirectFilter is a Java Servlet Filter that allows an admin to implement simple redirections in a web application, without any programming involved. It is very simple to set up and allow for a highly configurable usage. The setup is done in the WEB-INF/web.xml file of the web app. In some specific cases, it may even be the only content in this file.

Who is it for?

RedirectFilter is designed for anyone wanting a redirect in a servlet container. Use cases include, but are not limited to:

• Admins that manage a webserver whose servlet container is serving pages directly. People with an httpd in front of their container have other options, but they may still want to use it.
• Your domain is mydomain.com? You most certainly want your website to respond to http://mydomain.com as well as http://www.mydomain.com. Have a look at the example 1.
• Some URLs of your website have changed and you want people accessing the old URLs to be redirected to the new ones (including Google and other bots).
• You want some of your site to be viewed exclusively with https (and other parts exclusively with http). Have a look at the example 1.

How does it work?

First, you should make RedirectFilter available to your web app. This can be done by downloading pieroxy-tools.jar and drop it in the WEB-INF/lib of your web app.

At this point, you are ready to use it. You should edit your WEB-INF/web.xml file to setup your redirections. See the next section for detailed informations.
