I know how to pass parameters as a mydomain.com?id=2 request, however instead of the ?id=2 approach I'd like to implement a forward slash based approach to passing parameters in JSP Servlets? 
Similar to Stackoverflow:
stackoverflow.com/questions/20425024533/question-title-goes-here
This what I currently have:
JSP Page 1
<html>
    <head>
    </head>
  <body>
    <!--Other Page HTML-->
    <a href="PostServlet">Click here to view Post</a>
  </body>
</html>
PostServlet
public class PostServlet extends HttpServlet {
    public void doGet(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        String post_id = request.getParameter("id");
        RequestDispatcher rd = getServletContext().getRequestDispatcher("/BlogPost.jsp");  
        rd.forward(request, response);
    }
}
web.xml
  <servlet>
    <servlet-name>PostServlet</servlet-name>
    <servlet-class>com.myweb.web.servlet.PostServlet</servlet-class>
  </servlet>
  <servlet-mapping>
   <servlet-name>PostServlet</servlet-name>
   <url-pattern>/PostServlet</url-pattern>
  </servlet-mapping>
Taking Stackoverflow format as the example, can you show me how I could pass a value (id) in the format of mydomain.com/questions/id_goes_here/post_title_goes_here. 
Thanks guys!
