Welcome to the Q&A Forum

Hi, wonder if anyone can help? We have just changed our site which was hosted on IIS and the page url's were like this ( example.co.uk/Default.aspx?pagename=About-Us ). The new page url is example.co.uk/About-Us/ and is using Apache. The 301's our developer told us to use was in this format: RewriteCond %{REQUEST_URI} ^/Default.aspx$
RewriteCond %{QUERY_STRING} ^pagename=About-Us$
RewriteRule ^(.*)$  http://www.domain.co.uk/About-Us/ [R=301,L] This seemed to work from a 301 point of view; however it also seemed to allow both of the below URL's to give the same page! example.co.uk/About-Us/?pagename=About-Us example.co.uk/About-Us/ Webmaster Tools has now picked up on this and is seeing it a duplicate content. Can anyone help why it would be doing this please. I'm not totally clued up and our host/ developer cant understand it too. Many Thanks
