Set default frontpage to Front Page view I've setted the Default front page to the View Front Page, but when I go to www.mydomain.com the page don't redirects to www.mydomain.com/frontpage.

When I go and write www.mydomain.com/frontpage the Front Page view is displayed.

What is going wrong?
you need to set it here:

http://www.DOMAIN.com/admin/config/system/site-information

You set the "Default Front Page Link" there.

When you hit your root (/) url, it will not "redirect" to that custom url you set, but it will auto render the url you inputted. 

If you want to do a true redirect when hitting the frontpage you might have to do it via the .htaccess file as I'm not sure if there is module that can do a redirect from the frontpage.
