title: How to remove a parameter from HttpServletRequest request?
body: <p>In my web application I am sending two parameters: <code>action</code> and <code>productCode</code> from JSP to Servlet. Based on that action some processing will happen.</p>
  
  <p>Now after action is performed I am forwarding control to a JSP. The problem is that when the new JSP is opened the URL still contains the name of Servlet and the Parameters. So in case if someone refreshes the page, the same action will be performed again and again.</p>
  
  <p>If somehow I am able to remove the parameters from URL then I handled a no parameter situation in servlet.</p>
  
  <p>Can anyone please tell me how can I remove the parameter from request object?</p>
