Change domain name
 

I would Like to know how do i make to redirect all the past links from my previous domain.

Put this in an .htaccess file and it will do this for you.

This example if for all links in the old site directory of /forums, change to what you need.

Thank You. And what i have to do with the search engines in order that they dont think im using duplicated content??

A permanent redirect will not be counted as duplicate content.

Im using lightpd not apache
