title: How to remove Public render parameter from jsp or render phase of portlet class
body: <p>I have two portlets :
  1. Blog Portlet.
  2. Author Portlet.</p>
  
  <ul>
  <li>I used the concept of Public render parameter to send data (say key "urlTitle") from Blog portlet to Author portlet</li>
  <li>But after sending "urlTitle" from Blog portlet how can I remove the data from Public render parameter</li>
  </ul>
  
  <pre><code>In Blog Portlet
  EX code: view.jsp
  
  &lt;portlet:renderURL var="viewEntryURL"&gt;
      &lt;portlet:param name="struts_action" value="/blogs/view_entry" /&gt;
      &lt;portlet:param name="redirect" value="&lt;%= currentURL %&gt;" /&gt;
      &lt;portlet:param name="urlTitle" value="&lt;%= entry.getUrlTitle() %&gt;" /&gt;
  &lt;/portlet:renderURL&gt;
  
  &lt;a href="${viewEntryURL}"&gt;Send Data&lt;/a&gt;
  
  </code></pre>
  
  <p>Now how I can remove "urlTitle" form the public render parameter after data is sent.</p>
  
  <p>Please give feedback.
  -Thanks in advance</p>
