Links between multi-site sites with ShortCut-Nodes are creating wrong redirects

[dlubitz]

When changing URLs linked between two sites in a multi-site setup, the redirecthandler creates wrong redirects.

How to reproduce

1. Use a multi-site Setup with at least two websites and configured URLs
2. Create a ShortCut node in Site A (site-a.com) with a Link to a some Url on Site B (site-b.com) (e.g https://site-b.com/link.html)
3. Publish
4. Change the Link of the shortcut node in Site A to some different URL on Site B (e.g https://site-b.com/new-link.html)
5. Publish

What is the behavior

The redirecthandler creates a redirect entry for the Domain of Site A, but the Path of Site-B.
Moreover it tries to create multiple redirect entries, which lead to a "Duplicate entry" Exception on publish.

What is expected behavior

IMHO there shouldn't be redirects created at all, if the target of a shortcut has changed.

Solution

Maybe it is already a solution to exclude ShortCut-Nodes by default. But I'm afraid to miss a case where it might be useful.
