My advise is to not use an extra plugin, but just put the code in .htaccess

The lesser that PHP does the better

not sure I follow? www is a standard, more so, why not have both?

becuase this can lead to duplicate contest. so http://www.yourdomain.com/index.html will have same content but different url with http://yourdomain.com/index.html

It can be really bad too as many search engines penalize for this

You won't get penalized for duplicate content, but you will have your pagerank split across two different pages. Which means you won't be as high in the SERPs.

I've taken the www out of my address as well. On two of my site's anyway, one the other I force w's to appear.

No page ranking is both for www and without www and it works good without any penalize from google.I`ve pr5 for both www and without www.

Wow, that is great information, No-www is a great site name. It kinda makes me laugh.

[willyoumind]

WoW, I have never knew about this stuff until now...

Hmm..., I have to be more careful with the www. matter in the near future...

Thanks for the great information ;)
