指定不同机器的host后，还是获取不到数据，存在跨域请求的问题！

due to cross site origin limitations, the dashboard will only work if it's on the same subdomain as varnish agent (meaning you must use it with the -h option of varnish agent, preventing the usage of multiple servers). i've submitted a patch to varnish agent to fix this, but until it's merged, only one varnish backend is supported.

######谢谢回答。等待补丁。。######
