Unable to use a GET url-param

[Ajay Garg]

Hi All.

When I do the following call ::


https://username:password@1.2.3.4?upstream_protocol=http

I get a 500 error (on the browser-client), with the following seen in
/var/log/nginx/error.log (on nginx-server)

######################################################
2017/04/14 13:03:51 [error] 16039#16039: *1 invalid URL prefix in "://
127.0.0.1:5000", client: 182.69.5.226, server: , request: "GET
/cgi-bin/webproc HTTP/1.1", host: "1.2.3.4", referrer: "
https://1.2.3.4/?upstream_protocol=http"
######################################################


Following is the server-block section in /etc/nginx/conf.d/default.conf

######################################################
server {

                listen 443 ssl;

                ssl_certificate /etc/nginx/ssl/nginx.crt;
                ssl_certificate_key /etc/nginx/ssl/nginx.key;

                location / {

                        auth_basic 'Restricted';
                        auth_basic_user_file /etc/nginx/ssl/.htpasswd;

                        proxy_pass $arg_upstream_protocol://127.0.0.1:
$forwarded_port;
                }
        }
######################################################

It definitely looks that "upstream_protocol" parameter is not being picked
up by $arg_upstream_protocol.

What am I missing?
Will be grateful for pointers.


Thanks and Regards,
Ajay
