Google Pagerank w or w/o www ?

[jdk]

I am thinking about putting in a script that when a user enters in domain.com it will load up as www.domain.com. In a sense all of my links should be www.domain.com. Would this help or hurt my pagerank? Right now the site I am testing it on is a PR 6 w/www and PR 4 w/o www. Any opinions? Maybe from someone who has done this or thinks I shouldn't.

The best solution I have found is a 301 moved permanent redirect from the example.com to www.example.com. See for example 2 in

301 redirects are welcomed by the search engines. Other types of scripts to create redirects could cause the search engine to think you are spamming and lead to trouble

actually this issue has been raised several times and it has been a known problem and often "assumed" to hurt rankings due to duplicate content problem on the same site..301 redirect solves this issue

I agree, do the 301 from the lower PageRank version to the higher.

How does one accomplish this to avoid a duplicate domain indexing penalty from Google without disabling FP extensions? And why does this supposed remedy in the .htaccess file not work to restore the FP extensions?:

# -FrontPage-

RewriteEngine on
Options +FollowSymlinks
Options +ExecCGI

Is there another remedy that will preserve the FP extensions?

Back to the ORIGINAL question. All your links, internal and external should be conststant. It does not matter with www or not, just be the same internal and external otherwise the PR is split. This happend to me on one of my sites - I figured it out because my internal pages were PR5 and home page PR4. Once I fixed the link problem Home page PR6.
