Preload: Provide Info About Failed URLs
Is your feature request related to a problem? Please describe.
We now have the failed status in the database for URLs we attempt to preload. But we don't have any information about why they have failed. This makes troubleshooting difficult and time consuming if there are a lot of them. We would also need to know if these URLs should ultimately be excluded. If we keep re-trying them, it adds to the processing time for preload as a whole.
Describe the solution you'd like It would be great, if possible, to see what status code is returned from the server, or any other information that could provide a clue about why they failed.
Describe alternatives you've considered Manually checking URLs for issues, checking the debug log for issues, checking the server access logs for the response codes (not always possible depending on what access we have).
