Здравствуйте, весь сайт редиректит с www на без www, небходимо добавить в исключение robots.txt, так, что бы при доступы к www.site.com/robots.txt открывался www.site.com/robots.txt, а при site.com/robots.txt открывался site.com/robots.txt
В интернете посмотрел несколько примеров, исключает, но получается что-то одно, либо всё редиректит на www либо без www. Вот .htaccess
