[wp-hackers] Duplicate Content Issue - URLs work with dots and colons in it

[Guus (IFS)]

I can't imagine any undesirable behaviour with canonicals. It just tells 
search engines what's the 'best' url for a page if there are more url's 
leading to the same page. Very useful way to prevent duplicate content 
within a site.

What canonicals are is not obvious to anybody straight away, so that may be 
your issue. If you need any help with that just e-mail me.
