session中或者request中同名字的参数会被后来者覆盖

服务器1：

public void test1() throws IOException{
ActionContext ctx = ActionContext.getContext();
HttpServletRequest request = (HttpServletRequest)ctx.get(ServletActionContext.HTTP_REQUEST);   
HttpServletResponse response = (HttpServletResponse)ctx.get(ServletActionContext.HTTP_RESPONSE);

ctx.getSession().put("str", "1234567890+++++++实验成功了");

String port= request.getLocalPort()+"";
System.out.println("端口号为:"+port);
response.sendRedirect("http://localhost:8080/项目1 /命名空间1/test1.action"); 
}
public String test2() throws IOException{
ActionContext ctx = ActionContext.getContext();
HttpServletRequest request = (HttpServletRequest)ctx.get(ServletActionContext.HTTP_REQUEST);   
HttpServletResponse response = (HttpServletResponse)ctx.get(ServletActionContext.HTTP_RESPONSE);
ctx.getSession().put("str", "1234567890+++++++实验成功了???????覆盖掉就对了");

return "success";
}

服务器2

public void test1() throws IOException{
ActionContext ctx = ActionContext.getContext();
HttpServletRequest request = (HttpServletRequest)ctx.get(ServletActionContext.HTTP_REQUEST);   
HttpServletResponse response = (HttpServletResponse)ctx.get(ServletActionContext.HTTP_RESPONSE);
response.sendRedirect("http://localhost:8080/项目2 /命名空间2/test2.action");
