i have a product that is in preorder categories
the link is below
http://www.mysite.com/index.php?main...roducts_id=537

after the product release i have move the product into in stock categories that become another link

http://www.mysite.com/index.php?main...roducts_id=537

but i find out the first link still accessibile and exist,
it seems cause some problem for my google webmaster account

if you move one product from one categories from another categories, why the old link still accessible?? is there any solution for this? thanks
