Just got CMSMS setup and really like the experience. Congrats on a top job

This question isn't about SSL, but if someone lands on my site at http://example.com then my SSL seal doesn't show up properly, so I need to redirect them to http://www.example.com before it will appear.
Is there a 'correct' way in CMSMS of redirecting them to www.example.com? I have been looking at writing a UDT for this but it seemed pretty basic so I guess this is probably already in CMSMS.
Any replies appreciated,
Thanks!
