No follow links to external links.

Hi,

I apologize if this is off topic but I am in need of this solution.

Actually i want to apply Rel=nofollow to the external links under the text in the body.

Like:

This is to inform the Facebook that its a good page.

Thus the Rel=nofollow should be get applied to the facebook link i.e external link. But also it shouldn’t be applied on internal links.

Kindly let know the solution for it.
