I have a site running on IIS 6.0 server. Currently there are two live versions of each page. Upper case and Lower case versions like this:
www.site.com/page1 and www.site.com/Page1
These two pages show the exact same content. I am certain that Google sees these as two individual pages with duplicate content, as the lowercase version has Page Rank assigned and the upper case version has Pagerank grayed out.
How do I make sure that only the lowercase URL's are live?
