FireFox下面文件上传session丢失情况

前段时间在做项目的时候用到了JQuery的一个上传插件,但是呢,在火狐下面上传的时候在后台怎么也获取不到一些信息,后来才发现原来是session丢失了,我的解决方案很简单,直接是把要获取的信息加到上传的url后面,然后再从后来截取出来,这样就不会丢失了

image这些信息是要传递到后台处理的有用信息,但是session丢失了,用户信息后台获取不到,image通过加载url后面,具体代码如下:

 

<%@page import="com.sun.corba.se.spi.servicecontext.UEInfoServiceContext,java.util.*"%>
<%@ page language="java"  contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<c:set var="ctx" value="${pageContext.request.contextPath}"/>

    String videoinfo = request.getParameter("video_Info");
    List<String> list = (List<String>)request.getSession().getAttribute("videoName");
    String userAcc = request.getSession().getAttribute("userAccount").toString();
    String userName = request.getSession().getAttribute("userName").toString();
    String userOrg = request.getSession().getAttribute("userOrg").toString();
    String videoInfo = videoinfo + "~" + userName + "~" + userOrg;//要传递到后台的信息
