Pass Hidden parameters using response.sendRedirect()

Question

How would I pass hidden parameters? I want to call a page (test.jsp) but also pass 2 hidden parameters like a post.

response.sendRedirect(\"/content/test.jsp

Generally, you cannot send a POST request using sendRedirect() method. You can use RequestDispatcher to forward() requests with parameters within the same web application, same context.

RequestDispatcher dispatcher = servletContext().getRequestDispatcher("test.jsp");
dispatcher.forward(request, response);

The HTTP spec states that all redirects must be in the form of a GET (or HEAD). You can consider encrypting your query string parameters if security is an issue. Another way is you can POST to the target by having a hidden form with method POST and submitting it with javascript when the page is loaded.
