Quick and easy Joomla 1.5 Duplicate content fix?

[Gaveltek-173238]

www.massduitrialalwyers.com has a TON of duplicate content based on the way joomla 1.5 uses articles. Do you have a tried and true method to eliminate (automated would be preferred) the issues>? if not, might you suggest a plug in that takes care of the rel canonical?
Cheers

Done, done, and done. I hope to work together again soon.

Thanks Todd, you're very kind. Might be worth marking my response as a 'helpful answer' or the question as 'answered' since it still looks unanswered.

This code you posted seems to be working wonderfully. The link you posted is a thread to a plugin we dont use, but I so very appreciate your time. I would say you are doing just fine (regarding your comment about you not being and "expert") Thanks again!

I found somewhere a tip to put some code in the head.php file of your template (sorry can't find it at the mo, but I'm sure some Googling will discover it for you).

I ended up putting this in my head.php  (which I found here: templates/[MY TEMPLATE NAME]/blocks/head.php) BTW I didn't want the trailing slash in my URL - you'd need to tweak this if you do want it.

But you could probably get away with something simpler, there's some discussion about it here: http://www.brucerick.com/joomlas-sh404sef-and-canonical-links/

Oh and feel free to improve my php/regex...I'm no expert
