How can I redirect www to non www site?

On-Page SEO: What Redirect does Wordpress use as Default http:// to www etc?

• In Wordpress -> Settings -> General you set your homepage URL and site URL. If you go to the www or http:// it redirects the version set in your Wordpress settings. What sort of redirect is this though, not through Apache .htaccess????? I can't seem to find a reliable source and how is the redirection being done. I'm hoping it is a 301 but I can't find conclusive information. example site: http://www.webhostingreviews.net.au goes to http://webhostingreviews.net.au 1) I installed Firefox Live HTTP Headers but it doesn't show a redirect being executed. 2) I installed looked at the 'Net' tab in firebug and it doesn't show a redirect being executed. 3) If I go to a site like http://www.internetofficer.com/seo-tool/redirect-check/ it says it is a 301.... how is it determining that and is it correct??

• Answer:

  I can confirm that WordPress uses 301 redirects by default, and is in this case, as evidenced below. It's a highly search engine optimised platform - one of the many reasons for its popularity. As far as I'm aware, this is handled via .htaccess, which you should be sure not to edit directly (i.e. only make changes via Settings -> General).
