דרופל ישראל תשתיות תוכן קהילתיות פתוחות

on most drupal sites I notice that the internal links are all relative and not absolute.

This is very bed for seo because

/anyfolder (relative link)
and

www.domainname.com/anyfolder (absolute link)

when linking , are two other diffrent page that google index!!! the credits splits!

We want to avoid duplicate data on our sites, the solution will be pretty simple for someone
who knows php i guess.

Does anyone else notice this? am I wrong? there is a solution that I don't know of?

Thanks
