<DL>
<DD>Sets the portlet mode of a portlet to the given portlet mode.
 <p>
 Possible values are the standard portlet modes and any custom 
 portlet modes supported by the portal and the portlet. Portlets 
 must declare in the deployment descriptor the portlet modes they 
 support for each markup type.  
 Standard portlet modes are:
 <ul>
 <li>EDIT
 <li>HELP
 <li>VIEW
 </ul>
 <p>
 Note: The portlet may still be called in a different window
       state in the next render call, depending on the portlet container / portal.<DD><DL>

                   or the current user is not allowed to switch to this portlet mode.
                   To avoid this exception the portlet can check the allowed
                   portlet modes with <code>Request.isPortletModeAllowed()</code>.<DD><CODE>java.lang.IllegalStateException</CODE> - if the method is invoked after <code>sendRedirect</code> has been called.</DL>

public void <B>sendRedirect</B>(java.lang.String&nbsp;location)

<DL>
<DD>Instructs the portlet container to send a redirect response 
 to the client using the specified redirect location URL.  
 <p>
 This method only accepts an absolute URL (e.g. 
 <code>http://my.co/myportal/mywebap/myfolder/myresource.gif</code>)
 or a full path URI (e.g. <code>/myportal/mywebap/myfolder/myresource.gif</code>).
 If required, 
 the portlet container may encode the given URL before the 
 redirection is issued to the client.
 <p>
 The sendRedirect method can not be invoked after any of the 
 following methods of the ActionResponse interface has been called:
 <ul>
 <li>setPortletMode
 <li>setWindowState
 <li>setRenderParameter
 <li>setRenderParameters
 </ul><DD><DL>
