i need to redirecting from http to https, and append a "source" attribute for tracking (we're trying to figure out how the wrong requests are coming in)

this seems to work:

if ($query_string){
return 301 https://$host$request_uri&source=server1 ;
}
return 301 https://$host$request_uri?source=server1 ;

I'm just wondering if there is a more appropriate way
