TYPO3 Core

I already reported this a while ago: #89090. The issue has been closed as resolved, see https://review.typo3.org/c/Packages/TYPO3.CMS/+/61627

Was added in 10.1, see changelog: https://docs.typo3.org/c/typo3/cms-core/master/en-us/Changelog/10.1/Feature-89090-ReportsForConflictingRedirects.html

The patch does not really resolve the issue - meaning it does not prevent redirect loops. However it does provide some tools:

What you can do is use the commands redirect:checkintegrity and / or redirects:cleanup regularly to check theredirects and cleanup old redirects periodically (e.g. using the hit count or age of the redirect):

run:
typo3/sysext/core/bin/typo3

(I have not tested this yet).

@Wolfgang Podbregar Klinger After only about a week after updating to v10, redirect chaos has already rendered a page unavailable (redirect loops). This had to be manually resolved by an admin by removing unncessary redirects. It happened because URLs of pages including subpages were changed several times.

I had already anticipated problems with the automatic renaming of URLs (on subpages) and automatic redirect creation. I am afraid it is a real challenge to prevent editors from pointless multiple changes of URLs (which may be well intended but create problems). Will checkout sluggi extension.

I am not really happy with this. Wanted to stick to core solution.

You can use redirects:checkintegrity to find redirect loops.

I noticed, that it reports some problems with redirects which are false positives. Due to this, I find it difficult to work with this report.

I created an issue for that problem and a patch, would be great if someone could help with reviewing and testing:
