Are you sure that’s what you need? You can pass $https with  
fastcgi\_param or access it with perl’s variable method:  
$r-\>variable(‘https’) and set $ENV{..} accordingly.

Hi Alexandr  
Thanks Alexander.But I didnt get u completly. I tried  
by adding a ‘fastcgi\_param HTTPS on;’ but this variable is getting  
set for http request as well for https request. But i need to set for  
https request. Can u please elaborate ur statement so that i can easily  
understand it.

[http://nginx.org/en/docs/http/ngx\_http\_core\_module.html#variables](http://nginx.org/en/docs/http/ngx_http_core_module.html#variables)

```
fastcgi_param HTTPS $https if_not_empty; # for NGINX >= 1.1.11

```

For NGINX \< 1.1.11:

```
map $scheme $https_on {
    default '';
    https on;
}

fastcgi_param HTTPS $https_on;

```
