I am posting this in the 7.0 forum for now but assume it will apply to 7.1 as well unless changes were made.
Currently if one is logged into the site, and go to the site root; http://my_dolphin_site.com/ directly by typing it in their browser URL or clicking on a bookmark, they are sent to the home page with the message "Hello, User!" Some sites have it set so that if one is logged in and go to the site's domain they are redirected to their member page. Of course if the user clicks on the home page link; http://my_dolphin_site/index.php, they should go to the home page and not be redirected. The redirection should only happen if they go to http://my_dolphin_site.com/ and the user session cookie is set (they are logged into the system). How hard would it be to implement this in Dolphin?
