Java - 单击链接时向超链接servlet发送请求/响应

Question

我尝试使用谷歌搜索，我也搜索过StackOverflow，但我还没有找到这个问题的答案（也许我只是在搜索时不好？）。

Servlet A

public void doGet(HttpServletRequest request, HttpServletResponse response)
    throws IOException, ServletException
{
    PrintWriter out = response.getWriter();
    String sortBy = request.getParameter("sortBy");
    String orderBy = request.getParameter("orderBy");
    // Send request and response if this link is clicked
    out.println("<a href=\"/Fabflix/servlet/SortResults?sortBy=" 
                          + sortBy + "&orderBy=" + orderBy + "\">Title</a>);
    ArrayList<Movies> movies = ... //Fill up the movies arraylist
    request.setAttribute("movies", movies);
}

SortResults Servlet

public void doGet(HttpServletRequest request, HttpServletResponse response)
    throws IOException, ServletException
{
    // Receive request here so I can call:
    ArrayList<Movie> movies = (ArrayList<Movie>) request.getAttribute("movies");
}

如果仅在点击链接时才能从Servlet A发送请求/回复？
