CMS Made Simple Forums

I have a client who has a small issue. He's using flat urls, however in some cases, becuase google indexed the page before he added the url, he is getting the page appearing on two url types. For example...

;http://www.domain.co.uk/flat_url.html

;http://www.domain.co.uk/parent_page/flat_url.html

Is there a UDT or some other way to force the second one to reroute to the first. I am thinking not and that it needs doing in Google webmaster tools, but I thought it worth checking.

make sure you have the canonical URL stuff setup properly in templates.
