Backlinks question? Please help me

I have a wesbite site and have some backlinks to my http://mysite.com and other different backlinks to http://www.mysite.com. Will the backlinks on my http://mysite.com affect my www page?

Im am just asking because I have a backlink PR 6 going to my http://mysite, and was hoping it would help my www.

If there is a problem with it how can I solve it, with a redirect or something like that? Thanks.

You should 301 the non www to the www version as a good practice or vice versa. Below is an example of what I use.

Add this to your .htaccess file:

what babyboy said is dead right, if your not careful you can end up with duplicate content penalties due to www.blah.com and blah.com having the same content and yet both being indexed or having links pointing to them etc... it gets messy for the se's, be nice, 301 to the www version and ignore it
