Internal Links & PR

PR different for same page

[ecollier2012]

For years my homepage link to our phpbb forums looked like this.

http://example.com/forums

The page rank hovers around 4 for the above url.

However if I go same page using this url the PR is 0

http://example.com/forums/index.php

Should I be worried about this?
Will this trigger any duplicate content filters?
Should I be using
http://example.com/forums/index.php instead?

Thanks in Advance,
Ed

PR is definitely calculated by url; there isn't any technical definition for "page" and those are two different urls.

You know that one url is solidly indexed with a PR4, so I'd suggest that you change any links that point to index.php and repoint them to http://example.com/forums/ (I would also suggest always using the closing slash as a best practice.)

Google has been sorting this particular kind of duplicate a bit better lately, but they aren't the only search engine on the block. What I've suggested will hold up everywhere, and if you ever change to a different technology than PHP, your forum home page links will still work.
