U4-11134 - Preview url doesn't redirect to login page when not logged in

Relates to: U4-11090

What did you do? I previewed a page in the browser and copied the url of the preview. If pasted this url in a another browser.

What did you expect to happen? I expected to be redirected to the login page.

What actually happened? I see the navigation of the preview page, but don't see the actual preview (see screenshot)

I discovered this because a client sent me a preview link

Apparently this has been reported earlier, but has been closed due to inactivity : http://issues.umbraco.org/issue/U4-6812

Added a very dirty fix in this PR : https://github.com/umbraco/Umbraco-CMS/pull/2526

Is open for discussion.

in 7.10, preview is handled on the server side, previously this was a public endpoint using a static html page with an iframe. This server side change would just return an unauthorized page, but this update will redirect

  • log out
  • Go to /umbraco/preview, you will get redirected to the login page
  • log in, go and preview something and it should work
  • Copy the preview url you are looking at into a different browser where you are not logged in and ensure it redirects (to double check)

Confirmed redirects works as described and also confirmed the preview views are still loading as expected through the controller.
