Possible to determine which FastCGI server responded?

If I have a configuration like this for FastCGI, is it possible to
determine
which server responded to the request? Is there a variable that would
tell
this that I can use for nginx’s log?
upstream phpservers
{
server 10.1.1.50:5201;
server 10.1.1.51:5201;
}
