how to handle redirets for PPR requests on session time out

[saasira]

Hi,

   We are facing trouble in redirecting the users to login page for PPR requests after session time out.
   We are having a filter that redirects the users login ( jsp ) page if the user is not autheticated or the authentication timed out. But after redirecting,
   I'm seeing the following error in firebug console:       

["Invalid PPR response. The response-headers were:\nDate: Wed, 22 Jul 2009 09:52:49 GMT\nServer: Apache\n..."]Common1_2_7.js (line 10649)

["Error ", TypeError: a5 has no properties message=a5 has no properties, " delivering XML request status changed to ", function()]

 
       1.  I read on the internet that redirects on AJAX requests cannot be made server side and  can only be made via javascript, is that true?
       2.  I tried adding a PPR hook to identify if the response is regarding related to session timeout and if yes, then would change the document location to login page
              however, this is not working as expected; perhaps I'm doing something wrong.

              Here is what I'm doing:
                            

                  function register(){
                          TrPage.getInstance().getRequestQueue().addStateChangeListener(callbackMethod);
                   }

 

                   function callbackMethod(requestEvent)  
                   {
 
                       if(requestEvent.getStatus()=TrXMLRequestEvent.STATUS_COMPLETE)
                       {
                          
                                      var response=+requestEvent.getResponseXML());
                                      if(has info about session timeout)
                                             documnet.location="/login.jsp";
                       }
                  }

         
                  register();

                 But I'm getting error saying requestEvent.getStatus() is not defined.

 

 

              Can some one help me how to redirect users to login page on PPR requestts?

Thanks and Regards,

Hi Samba,

 

Trinidads built-in ppr-Framework has the ability to send redirects initiated by the server.

The only steps you have to do are:

·         check if it is a ppr-request

o    on “normal” requests use response.sendRedirect

o    on ppr-requests send ppr-Message containing <redirect>

 

Following code examples works on our site

 

    final boolean isPartialRequest =  "true".equals(req.getHeader("Tr-XHR-Message"));

    if (isPartialRequest) {

      final PrintWriter writer = resp.getWriter();

      final XmlResponseWriter rw = new XmlResponseWriter(writer, "UTF-8");

      rw.startDocument();       

      rw.write("<?Tr-XHR-Response-Type ?>\n");

      rw.startElement("redirect", null);

      rw.writeText(pageURL, null);

      rw.endElement("redirect");

      rw.endDocument();

      rw.close();

    }

    else {       

      resp.sendRedirect(pageURL);

    }

 

Kind regards

 

  Harald

Great news!
         It would have meant much more to me if this were implemented by now.
         Anyway, this is certainly the best way to go for fixing this issue.

Harald, I just realized that the XmlResponseWriter you referrred to is from trinidad jars; We are actually having a centralized valve at tomcat level that does the redirection.

 We would want that piece of code to be independent of any dependencies on any of the UI frameworks.

 Is it possible to write some thing like:

     final boolean isPartialRequest =  "true".equals(req.getHeader("Tr-XHR-Message"));

     response.setContentType("text/xml");
    PrintWriterout = response.getWriter();
    if (isPartialRequest) {

    out.println("<?xml version=\"1.0\"?>");
    out.println("<?Tr-XHR-Response-Type ?>\n");

    out.println("<redirect>");
    out.println("</pageURL>");

    out.println("</redirect>");
    out.close();

         }else {       

           response.sendRedirect(pageURL);

      }

Thanks and Regards,
Samba

Hi Samba,

 

I’m not really sure if XmlResponseWriter would do more than your suggestion in this case.

Maybe it writes some additional state or java script.

 

I would suggest to first implement the solution using XmlResponseWriter und try to inspect the generated XML-Response (i.e. using Firebug) and probably the response headers.

If there is no additional content in the response (or headers), your solution should work as well.

 

 

Regards

 

  Harald

Subject: how to handle redirets for PPR requests on session time out

 

Hi,

   We are facing trouble in redirecting the users to login page for PPR requests after session time out.
   We are having a filter that redirects the users login ( jsp ) page if the user is not autheticated or the authentication timed out. But after redirecting,
   I'm seeing the following error in firebug console:       

["Invalid PPR response. The response-headers were:\nDate: Wed, 22 Jul 2009 09:52:49 GMT\nServer: Apache\n..."]Common1_2_7.js (line 10649)

["Error ", TypeError: a5 has no properties message=a5 has no properties, " delivering XML request status changed to ", function()]

 
       1.  I read on the internet that redirects on AJAX requests cannot be made server side and  can only be made via javascript, is that true?
       2.  I tried adding a PPR hook to identify if the response is regarding related to session timeout and if yes, then would change the document location to login page
              however, this is not working as expected; perhaps I'm doing something wrong.

              Here is what I'm doing:
                            

                  function register(){
                          TrPage.getInstance().getRequestQueue().addStateChangeListener(callbackMethod);
                   }

 

                   function callbackMethod(requestEvent)  
                   {
 
                       if(requestEvent.getStatus()=TrXMLRequestEvent.STATUS_COMPLETE)
                       {
                          
                                      var response=+requestEvent.getResponseXML());
                                      if(has info about session timeout)
                                             documnet.location="/login.jsp";
                       }
                  }

         
                  register();

                 But I'm getting error saying requestEvent.getStatus() is not defined.

 

 

              Can some one help me how to redirect users to login page on PPR requestts?

Thanks and Regards,
Samba

Hi Samba,

 

I’m not really sure if XmlResponseWriter would do more than your suggestion in this case.

Maybe it writes some additional state or java script.

 

I would suggest to first implement the solution using XmlResponseWriter und try to inspect the generated XML-Response (i.e. using Firebug) and probably the response headers.

If there is no additional content in the response (or headers), your solution should work as well.

 

 

Regards

Harald, I just realized that the XmlResponseWriter you referrred to is from trinidad jars; We are actually having a centralized valve at tomcat level that does the redirection.

 We would want that piece of code to be independent of any dependencies on any of the UI frameworks.

 Is it possible to write some thing like:

     final boolean isPartialRequest =  "true".equals(req.getHeader("Tr-XHR-Message"));

     response.setContentType("text/xml");

    PrintWriterout = response.getWriter();

    if (isPartialRequest) {

    out.println("<?xml version=\"1.0\"?>");

    out.println("<?Tr-XHR-Response-Type ?>\n");

    out.println("<redirect>");

    out.println("</pageURL>");

    out.println("</redirect>");

    out.close();

         }else {       

           response.sendRedirect(pageURL);

      }

Thanks and Regards,
Samba

Hi Samba,

 

Trinidads built-in ppr-Framework has the ability to send redirects initiated by the server.

The only steps you have to do are:

·         check if it is a ppr-request

o    on “normal” requests use response.sendRedirect

o    on ppr-requests send ppr-Message containing <redirect>

 

Following code examples works on our site

 

    final boolean isPartialRequest =  "true".equals(req.getHeader("Tr-XHR-Message"));

    if (isPartialRequest) {

      final PrintWriter writer = resp.getWriter();

      final XmlResponseWriter rw = new XmlResponseWriter(writer, "UTF-8");

      rw.startDocument();       

      rw.write("<?Tr-XHR-Response-Type ?>\n");

      rw.startElement("redirect", null);

      rw.writeText(pageURL, null);

      rw.endElement("redirect");

      rw.endDocument();

      rw.close();

    }

    else {       

      resp.sendRedirect(pageURL);

    }

 

Kind regards
