phpipam behind a load balancer which handles ssl offloading

phpipam has support for ssl offloading, via X-Forwarded-For header .

  public function createURL () {
                # reset url for base
                if($_SERVER['SERVER_PORT'] == "443")            { $url = "https://$_SERVER[HTTP_HOST]"; }
                // reverse proxy doing SSL offloading
                elseif(isset($_SERVER['HTTP_X_FORWARDED_PROTO']) && $_SERVER['HTTP_X_FORWARDED_PROTO'] == 'https')      { $url = "https://$_SERVER[SERVER_NAME]"; }
                elseif(isset($_SERVER['HTTP_X_SECURE_REQUEST'])  && $_SERVER['HTTP_X_SECURE_REQUEST'] == 'true')        { $url = "https://$_SERVER[SERVER_NAME]"; }
                // custom port
                elseif($_SERVER['SERVER_PORT']!="80")           { $url = "http://$_SERVER[SERVER_NAME]:$_SERVER[SERVER_PORT]"; }
                // normal http

Unfortunately, some don't follow this or have been configured for this, which results in phpipam loading incorrectly. To workaround this issue, edit config.php

$_SERVER['HTTP_X_FORWARDED_PROTO'] = "https";

And now, back to life.
