Cookies not set when port is used in URL

[LRP-sgravel]

My CI test webserver is on port 8000 so my tests continually failed but only on this server. The reason is that Firefox doesn't set cookies when there is a port in the domain. I'm not sure what other browsers could be affected.

I didn't want to fork for this simple fix but here it is for Experiments.php (notice the addition of a parse_url call when using $_SERVER):

    /**
     * @return string
     */
    public static function getDomainName() {
        if(static::$domainName == 'auto') {
            return isset($_SERVER['HTTP_HOST']) ? parse_url(strtolower($_SERVER['HTTP_HOST']), PHP_URL_HOST) : null;
        } elseif(static::$domainName) {
            return static::$domainName;
        } else {
            throw new UnexpectedValueException('Unable to determine domain name, please provide one via setDomainName()!');
        }
    }

Sorry, it should have been:

return isset($_SERVER['HTTP_HOST']) ? parse_url(strtolower('http://' . $_SERVER['HTTP_HOST']), PHP_URL_HOST) : null;

Missing 'http://' prefix messes up parse_url
