The HttpServletRequestobject cannot be changed. But you can add additional attributes to it, using HttpServletRequest.setAttribute() method. This is useful, when you forward the request to another page:

RequestDispatcher dispatcher = httpServletRequest
    .getRequestDispatcher("/url/to/new/page");
dispatcher.forward(httpServletRequest, httpServletResponse);

The receiving servlet then can read the additional attributes, you set. It has to be in the same web application on the same server instance.
