body: <p>Basically I have 2 questions regarding grails filters.</p>
  
  <ol>
  <li>According to grails documentation you can do something like below in a filter</li>
  </ol>
  
  <blockquote>
  <pre><code>if (userId != paramsUserId) {
      flash.message = "You can only modify yourself"
      redirect(action: 'list')
      return false
  }
  </code></pre>
  </blockquote>
  
  <p>If the above condition is true then how will the return statement get executed ?</p>
  
  <ol start="2">
  <li>Can I have a redirect in my filter to a some action which also has a redirect ?</li>
  </ol>
