ueditor图片上传跨域问题

ueditor 置于A域，图片置于B域，B域需放flash跨域策略文件crossdomain.xml，如下

<?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="*.xx1.com" />
  <allow-access-from domain="*.xx2.com" />
  <allow-http-request-headers-from domain="*" headers="*"/>
</cross-domain-policy>

修改ueditor配置文件ueditor.config.js

        //图片上传配置区
        ,imageUrl:"http://abupload.xxx.com/imageUp.php"             //图片上传提交地址
        ,imagePath:"http://abupload.xxx.com/"
