I am using Nginx + php-fpm setup

I noticed that I could set fastcgi_param however fastcgi_pass_header is not being set. I tried to print $_SERVER in php which has only fastcgi_params and not fastcgi_pass_headers.

My queries are:
1. Is there any additional configuration parameter needed for fastcgi_pass_headers? I have set 'underscores_in_headers on;', however headers I am trying to set don't have underscores. I tried to manipulate client request headers (through TamperData) it works fine as by default it is on.

2. Is there any other way to check (apart from _SERVER) to check if headers are set properly while passing to php-fpm?

Any help is appreciated.

I have following configuration:

fastcgi_param SERVER_PORT $server_port;
fastcgi_param SERVER_NAME $server_name;
.....
.....

fastcgi_pass_header Authorization;
fastcgi_pass_header Host;

fastcgi_pass_header X-Real-IP;
fastcgi_pass_header X-Forwarded-For;


location block looks like following:


location ~ \.php(.*)$ {
try_files $uri =404;

root /home/myntradomain/public_html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include /etc/nginx/fastcgi_params;
}
