forward vs. include

Forward

• Forwards a request from a Servlet to another resource (Servlet, JSP file, or HTML file) on the server.
• forward should be called before the response has been committed to the client (before response body output has been flushed)

Include

• Includes the content of a resource (servlet, JSP page, HTML file) in the response.
• The included servlet cannot change the response status code or set headers.
