listen spdy per server_name

[Richard Kearsley]

Hi
It seems that if I have 2 server {} sections, one with spdy enabled and 
one without, spdy is still accepted on the second

server
{
         server_name "";
         listen 80;
         listen 443 ssl spdy;
}
server
{
         server_name "something.com";
         listen 80;
         listen 443 ssl;
}

a request to something.com still allows spdy, but I want it to fall back 
to normal https in this case
Is this correct behaviour?

Thanks
Richard
