title: Implementing URL slugs in Magento
body: <p>How can I implement a "slug" (I believe is the right term) in the URL? Say the URL is</p>
  
  <pre><code>www.example.com/module/controller/action1/123  
  </code></pre>
  
  <p>or  </p>
  
  <pre><code>www.example.com/module/controller/action1/123/abc
  </code></pre>
  
  <p>and I want my <code>action1</code> controller action method hit, and I want to be able to access the value <code>123</code>, or even <code>123</code> and <code>abc</code>, how could I do that?</p>
