You should have a look at the 404 Redirect Handler addon. 

You can catch 404s and redirect them. 

You can also setup (in Episerver) redirects from one URL to another and it should be able to do what you are looking for.

My only question - Why do you even have 302 redirects for unpublished pages? Unpublished pages will return 404 anyway...

Hi Marcus

thanks for your answer, we use 302 redirect because if we use the unpublished pages we do not get 404 but we get the episerver login screen.

so we need to redirect all unpublished to our 404 pages.

our marketing guys says it is a bit problematic when google bot see the 302 before the 404.

many thanks

That is not the behaviour I am seeing.

If I create a new page and don't publish it, when I navigate to it (e.g. http://www.mysite.com/newpage) I get a 404.

If I publish it then I get a 200 and the page

If I expire it then I get a 404 again.

Are you sure that you are not trying to hit the unpublished page using the CMS link when you are not logged in (that would cause the behaviour you are seeing). The link would look something like http://www.mysite.com/EPiServer/Cms/#context=epi.cms.contentdata:///439&viewsetting=viewlanguage:///en
