jsp:forwardredirects the servlet Request and Servlet Response to another resource specified in the tag. The path of the resource is ‘relative path’. The output generated by current JSP will be discarded.jsp:includeprocesses the resource as part of the current jsp. It include the output generated by resource, which is specified in the Tag to the current JSP
In both the cases single Request process multiple resources.
