The jsp:include action work as a subroutine, the Java servlet temporarily
passes the request and response to the specified JSP/Servlet. Control is
then returned back to the current JSP page.
The jsp:param action is used to add the specific parameter to current
request. The jsp:param tag can be used inside a jsp:include, jsp:forward or jsp:params block.
The jsp:forward tag is used to hand off the request and response to another JSP or servlet.
In this case the request never return to the calling JSP page.
