Duplicate content / title caused by CAPITALS

[jonny512379]

What is the best way to stop duplicate content warning (and Google classing them as duplicate content), when it is caused by CAPITALS (i.e www.domain.com/Directory & www.domain.com/directory ).

I try to always use lower case (unless a place name then i use Capitals for the first letter), but it looks like i have slipped up and got some mixed up and other sites will also be linking to Capitals

Thanks

Jon

Probably, you can set pointing to the lower case URL.

So, even though the upper case and lower case are actually no difference for us, search engines may assume the lower case url will be the primary one.

Other alternative maybe to have a regular expression to redirect/rewrite the capitals into lower case.
