[tim wallace]

Hello, everybody, I really need your help to do 301 redirect using .htaccess under such situation. When I delete www in the URL, the page would be turned into the homepage. For example, the right URL is www(dot)abc.com/a-b-c-d-e-f.html, when I delete the www and enter again, the URL turn into www(dot)abc.com(the homepage), not the result I want to get like this: www(dot)abc.com/a-b-c-d-e-f.html
