Don't think they have changed it so it should be a 301 with 6R2 as well...Haven't verified it though...
Not sure if my 6R2 is messed up somehow, but when using Shortcut to other page, I'm never redirected if I enter the URL manually, but it uses the content etc from the "other" page.
What is Shortcut to page in EPiServer CMS/Link to page on another Web site? Is it a 301 or a 302 redirect?
