Nginx return empty

[fhding618]

I hava a website on a remote server and  set the nginx servername
"xiangyingdu.com abc.com"
server{
    listen 80;
    server_name  xiangyingdu.com abc.com;
     ... ...
     ... ...
}

I set host in my local pc.
115.12.**.** xiangyingdu.com
115.12.**.** abc.com

Then I visit abc.com is OK, but the xiangyingdu.com always return code "200
0"

125.**.**.130 - - [24/Aug/2013:00:39:08 +0800] "GET / HTTP/1.1" 200 0 "-"

Now I don't know what wrong is....
