That may be common, but its a bad practice that needs to go away.  Each web page 
should have exactly 1 url at which it lives (archives and backups 
notwithstanding); any other urls by which it may be reached should invoke a 
client-side redirect to that 1 url, not just serve a copy.  Doing this correctly 
is also quite easy. -- Darren Duncan
