I have the main domain name as Dublinnites.ie and two other domans that redirect to the main one, Dublinnites.com and Dublinnights.ie, google has indexed the site for the Dublinnites.com domain, when i click on say www.dublinnites.com/disclaimer.php it will show up a 404 error, will these pages just fall out of google when google crawls realises that the two domains are just redirecting??
