Interestingly,  Alexa  merge the two while Netscraft insist that  the  two
possibilities  (URL's)  are completely separate. I suppose that  the  best
practice  is  to always link consistently or use the CMS (or a script)  to
redirect  from  one to the other (this protects you in case  other  people
link to your page or enter it by direct request, e.g. address bar).

Merging the two can be a miserable and frustrating experience if your site
is highly fragmented. That's why I never bother with it, personally...
