proper way to redirect from http to https w/query string notifier

[Jonathan Vanasco]

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
