In Java I can write a really basic JSP index.jsp like so:
index.jsp
<% request.getRequestDispatcher(\"/home.action\").forward(request, response); %>
Concepts Redirect and Forward like in Java, can be achievable in PHP too.
Redirect :: header("Location: redirect.php"); -- (URL in address bar changes)
header("Location: redirect.php");
Forward :: include forward.php ; -- (URL unchanged at address bar)
include forward.php ;
Its manageable with this & other programming logics
