最近项目里涉及flash插件的批量上传，期间碰到不少问题，经过一番调研都一一解开，这里便记录下。

在项目根目录添加crossdomain.xml，里面加上允许访问的域名，主要是为了防止项目的静态文件和主程序文件不是放在一个域名下（如主域名为www.test.com，而静态文件放在static.test.com）。

<?xml version="1.0"?><!DOCTYPE cross-domain-policy SYSTEM "http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd"><cross-domain-policy><allow-access-from domain="www.test.con" /><allow-access-from domain="*.test.com" /></cross-domain-policy>

在火狐浏览器下，使用flash的批量上传失败，是由于session失效的缘故，而项目大多在入口做了是否登录的判断，没有session便进不去上传文件的方法，因此上传失败。解法为在批量上传的调用js里加上当前的session_id，在项目入口处加上相应的判断。
