1067	behaviour of location + proxy_pass with a variable does not match behaviour with hardcoded value	allan-simon@…		"Here's a minimal case to reproduce 


{{{
server {
  listen 80;
  location /myservice/ {
    proxy_pass http://127.0.0.1:8080/;
  }
}
}}}

with a    nc -l 8080 acting as proxified proxy

the following command 

curl http://localhost/myservice/foo/far

show on netcat side, as expected 


{{{
GET /foo/bar HTTP/1.0
Host: 127.0.0.1:8080
Connection: close
User-Agent: curl/7.43.0
Accept: */*


}}}
 
now if i use a variable to store my proxified service's domain like this


{{{
server {
  listen 80;
  set $MY_SERVICE ""127.0.0.1:8080"";
  location /myservice/ {
    proxy_pass http://$MY_SERVICE/;
  }
}
}}}
 

now regardless of the URI, the proxified value will always be


{{{
GET / HTTP/1.0
Host: 127.0.0.1:8080
Connection: close
User-Agent: curl/7.43.0
Accept: */*


}}}

notice now the GET has become / , though it should be GET /foo/bar"	defect	closed	minor		nginx-core	1.9.x	invalid	location variables		"Linux all-MacBookPro 4.2.0-42-generic #49-Ubuntu SMP Tue Jun 28 21:26:26 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
