TYPO3 Core

Setup:

• Site with empty ("/") base.
• A page in the page tree within the site.

Steps to reproduce

• Change the site base to a full qualified URL (like "https://example.com")
• Change the slug of a page in the page tree

What happens:

• A redirect with the source_host of the current page will be created.

What should happen instead:

• The source_host of the created redirect must be "*", because the original URL of the page did not resolve to any specific domain.

Example:

• Site with base "/" and page with slug "/foo" can be accessed with any domain and path /foo
• After the site base changed the page can only be accessed with the new base. The new page url is "https://example.com/foo"
• The redirect must therefore redirect from "http(s)://*/foo" to "https://example.com/foo"
• BUT: The source_host of the generated redirect includes the new domain, which prevents redirects from matching any other previous host/domain.

Implications:

• The generation of redirects has to check the last valid URL of the page before any change has been made to the page and its site.
