Make dir sessions in runtime not make sense #240
Description
Because redis session inherits the default session class, it ends up creating the session folder, this could be removed.
I'm in doubt about the best way to remove this abstraction would be unnecessary, as it's all tied to file sessions.
public function setSavePath($value)
{
$path = Yii::getAlias($value);
if (is_dir($path)) {
session_save_path($path);
} else {
throw new InvalidArgumentException("Session save path is not a valid directory: $value");
}
}
