Is this 302 re-direct on Magento a problem?

[MoA]

The SEOmoz crawler has pointed out this warning on my Magento store..

http://mydomain.co.uk

redirects to

http://www.mydomain.co.uk

Is this a problem? My site is new, so don't want to get penalised this early on! Any advice appreciated.

Yeah, that's a problem.  That means if people put links to http://mydomain.co.uk, they won't be passing their link juice on to http://www.mydomain.co.uk if the redirect is a 302 (temporary) redirect.  You should configure this to be a 301 (permanent) redirect.

I read just recently on tehBing blog, that Bing will treat a 302 that has been in place for a long time as a 301, and visa versa, if a 301 keeps changing they will trat it as a 302

But I have no idea if Google does anything like this.
