Hello,

location ~ ^/api/v(\d)/foo/bar/(.\*) {  
proxy\_set\_header X-Real-IP $remote\_addr;  
proxy\_set\_header X-Forwarded-For $proxy\_add\_x\_forwarded\_for;  
proxy\_set\_header Host $http\_host;  
proxy\_redirect off;  
proxy\_max\_temp\_file\_size 0;  
proxy\_pass  
http://$http\_x\_destination\_host:$http\_x\_destination\_port/$uri;  
}

What I’m looking for is to have X-Destination-Host and  
X-Destination-Port contaning the exact host where to proxy\_pass.  
Since currently it doesn’t seem to get picked up I would like to ask if  
is this appear correct (not counting security implications).

Thanks.
