Hello, my upstream server replies with this:

HTTP/1.1 200 OK.  
Server: test.  
Date: Sat, 28 Nov 2015 00:05:55 GMT.  
Content-Type: application/json.  
Content-Length: 0.  
Connection: close.  
X-ExtraInfo: domain\_name=[test1.com](http://test1.com)  
;domain\_id=1000;user\_name=user1;user\_id=10001001.  
X-Accel-Redirect: /internal\_redirect/192.168.2.153:7777.  
Access-Control-Allow-Origin: [https://192.168.2.153:445](https://192.168.2.153:445).  
Access-Control-Allow-Credentials: true.

which I handle with this:

location ~ ^/internal\_redirect/(.\*) {  
internal;  
proxy\_pass http://$1$is\_args$args;  
}

However, I want to pass X-ExtraInfo to the target upstream server so i  
tried:  
proxy\_set\_header X-ExtraInfo  
$sent\_http\_x\_extrainfo;  
and even:  
proxy\_set\_header X-ExtraInfo  
$http\_x\_extrainfo;  
but none of them worked.  
So, is there a way to get headers from X-Accel-Redirect replies?

Obs: I can workaround this passing the ExtraInfo as arguments in the  
target  
URL but I want try to rely on the current interface of the target  
upstream  
server.

Regards,  
Takeshi

Hello,  
I have found the solution in the openresty google group:
