Could somebody suggest the easiest method to redirect the non-www towards the www in Joomla? I'd normally do that within the .htaccess file but I am unsure whether it's the easiest method to get it done with dynamic websites.

Thank you Rob

There's extra time to do this, you'll find it here around the Joomla extension directory

i'd do that through the .htaccess file its the easiest way as then Google will just index your www.xxx site.
