some detailed means for managing the duplicated content properly?

[fianliao]

Any URL has the potential to be counted by search engines. Two URLs referring to the same content will look like duplicated, unless you manage them properly. So could you provide some detailed means for managing the duplicated content properly? Thanks a lot.

I don't think there is a reason to have two different URL's from the same content. This actually means that you are going to affect the URL's rankings intentionally which may not be seen in the near future but will be seen in the long run. The best possible way to manage duplicate content I can think of is to redirect one URL to the other.
