Newby working for a couple weeks. Any guidance really appreciated.

Nginx is not preserving the url from redirected backend tomcat server.

Nginx url: [//develop-application.example.com/](https://develop-application.example.com/)

Backend tomcat url: [//application.example.com/](https://application.example.com/)

tomcat redirects url: [//application.example.com/application](https://application.example.com/application)

I want the client browser url to always remain  
[https://develop-application.example.com/application](https://develop-application.example.com/application) no matter what  
returns  
from tomcat.

Config:

server {  
listen 443 proxy\_protocol;  
set\_real\_ip\_from 0.0.0.0/0;  
real\_ip\_header proxy\_protocol;  
access\_log  
/var/log/nginx/develop-application.example.com.https.access.log elb\_log;

```
    server_name develop-application.example.com;

    ssl on;
    ssl_certificate /etc/nginx/ssl/example.com.crt.chained;
    ssl_certificate_key /etc/nginx/ssl/example.com.key;
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
    ssl_ciphers 'EECDH+AESGCM:EDH+AESGCM:AES256+EECDH:AES256+EDH';
    ssl_prefer_server_ciphers on;
    ssl_session_cache shared:SSL:10m;

    location / {

        proxy_pass https://application.example.com/;
        proxy_redirect https://application.example.com/

```

[https://develop-application.example.com/](https://develop-application.example.com/);  
proxy\_set\_header Host $http\_host;

```
        }

```

}

Your proxy\_redirect rule does not match what is returned from your  
backend.  
Remove the “https” prefix maybe?  
Since you want to redirect to the current hostname, you could also use  
the  
$host variable.  
Then, since your server block is configured to only listen on SSL port,  
you  
could also take advantage of the $scheme variable.

## proxy\_redirect [//application.example.com/](https://application.example.com/) $scheme://$host/;
