Access Forbidden XAMPP Error while try to chnage the security

Access forbidden!

You don't have permission to access the requested object. It is either read-protected or not readable by the server.

If you think this is a server error, please contact the webmaster.

Error 403

localhost
Apache/2.2.11 (Win32) DAV/2 mod_ssl/2.2.11 OpenSSL/0.9.8i mod_autoindex_color PHP/5.2.8

How to get access to the XAMPP Security Page

1. Navigate to your xampp\apache\conf\extra folder
2. Using a text editor, open httpd-xampp.conf
3. Find the following line:
   

   Allow from localhost

4. Change the line to:
   

   Allow from 127.0.0.1

5. Save the file and restart your XAMPP server
6. Try to access http://localhost/security/lang.php?en

You should now have no problems accessing the XAMPP Security Page via localhost or 127.0.0.1

What are the different cases for using sendRedirect() vs. getRequestDispatcher()?

When you want to preserve the current request/response objects and transfer them to another resource WITHIN the context, you must use getRequestDispatcher.

If you want to dispatch to resources OUTSIDE the context, then you must use sendRedirect. In this case you won't be sending the original request/response objects, but you will be sending a header asking to the browser to issue a request to the new URL.

If you don't need to preserve the request/response objects, you can use either.
