hello.
i have a particular error in my php logs:

Undefined index: HTTP_HOST in /var/www/codoforum/sys/CODOF/Cookie.php on line 67
 Undefined index: HTTP_HOST in /var/www/codoforum/sys/load.php on line 23

after investigations, my server never send HTTP_HOST variable, as it's a protection against host poisoning ( https://ellislab.com/blog/entry/http-host-and-server-name-security-issues)

is there a way to setup the real host name in a config file ?

thanks

The domain variable is not even used so we simply deleted those lines.

You can do the same for Cookie.php file

As for load.php file, you can manually edit the file and set your host

thanks @adesh1414127033 for the answer.

Maybe adding

define('CODO_URL', 'mydomain');

in constants.php or config.php

and correct codoforum/sys/load.php line 23

$path = $protocol . CODO_URL . $_SERVER['SCRIPT_NAME'];

and move it to line 29

more 'clean' if we upgrade ?

Yes, we will do that.

For those users who have HTTP_HOST, we will automatically update constants.php file with that value and for others, they can provide it during installation.
