Google see my pages as dublicated content

[alfanexus]

My problem is that I have a site located on a asp.net windows server, and overtime the same page has become indexed by google as different pages. Ex.

www.mysite.com/articles/article?id=3473
mysite.com/articles/article?id=3473
www.MySite.com/Articles/Article?id=3473
MySite.com/Articles/Article?id=3473

Its the sime page but google might think I have several pages showing dublicate content.

Is there any way to solve this problem? Maby a tool that makes the server always show the url without the www and always without capital letters?

Your best bet is to perform a 301 redirect on the server so that any non www links forward to the www domain. This can be implemented through the server or through code. I'd normally set this up through the server myself but code is good if you dont have access.

Theres loads of website out there explaining how to do this. Google 'asp 301 redirect' and you'll no doubt find a solution.
