$https variable?

Server NGINX

It would be great if there was an $https variable that was “on” or “off”
(or “”) so you could do something like this:

fastcgi_param HTTPS $https;

Because currently telling PHP https is enabled is much harder,
especially for those that prefer to have a single server{} block for
both HTTP and HTTPS.

Typically PHP uses $_SERVER[‘HTTPS’] === ‘on’ to detect whether or not
HTTPS is enabled.

Igor proposed this a while ago:

on the global level (in http{} block)
map $scheme $php_https { https on; http off; }

then in fastcgi_params
fastcgi_param HTTPS $php_https;

Unfortunately, PHP code in many known packages (such as Moodle)
sometimes relies on the wrong assumption:

$HTTPS = isset($HTTP_SERVER_VARS[‘HTTPS’]) ? $HTTP_SERVER_VARS[‘HTTPS’]
: ‘off’;

Because in Apache HTTPS variable is never submitted at all in http mode
and coders believe this is enough information to check. So, is there a
way to never submit HTTPS=off at all if HTTPS is not present?

fastcgi_param HTTPS $php_https;
