Reloading nginx configuration: nginx: [emerg] unknown "php_https" variable

[Christian Becker]

Hi,

I'm trying to run dokuwiki with https.

On the nginx-wiki there is a doku about this: http://wiki.nginx.org/Dokuwiki

Problem: When including "fastcgi_param HTTPS $php_https;  there is this error while reloading nginx:

Reloading nginx configuration: nginx: [emerg] unknown "php_https" variable 

Any idea, why this happend?

Thanks allot
Chris
