代码如下预计在Firefox中。但在IE浏览器中，Chrome和Opera会像400 Bad Request一样抛出异常。我在这上花了2天但没有找到任何修复。 （它的跨域托管站点位于远程，可从本地主机访问）
请帮帮我吗？
谢谢

The code works as expected in Firefox. But in IE, Chrome and Opera throws exception like 400 Bad Request. I spent 2 days on this but not found any fix. (Its cross Domain hosted site in remote and accessed from the local host)
Please help me out?
Thanks
