Allows you to rewrite URLs before they get to your code. It is a very powerful tool just like Apache's mod_rewrite.

Example 1:

<module>
	<name>rewrite</name>
	<author>Hamed Abdollahpour</author>
	<class>ir.xweb.module.RewriteModule</class>
	<properties>
		<property key="/start" value="index.html" />
		<property key="/download/(.*)" value="/api?api=resource&amp;download=public/" />
	</properties>
</module>

What is URL Rewriting?

URL rewriting is very common with Apache Web Server (see mod_rewrite's rewriting guide) but has not been possible in most java web application servers. The main things it is used for are:

  • URL Tidyness / URL Abstraction - keep URLs tidy irrespective of the underlying technology or framework (JSP, Servlet, Struts etc).
  • Browser Detection - Allows you to rewrite URLs based on request HTTP headers (such as user-agent or charset).
  • Date based rewriting - Allows you to forward or redirect to other URL's based on the date/time (good for planned outages).
  • Moved content - enable a graceful move of content or even a change in CMS.
  • Tiny/Friendly URL's (i.e. blah.com/latest can be redirected to blah.com/download/ver1.2.46.2/setup.exe)
  • A Servlet mapping engine (see Method Invocation)
  • This document based on UrlRewriteFilter project
