'8' could be one of several (pretty many) different errors. The value
aggregates / simplifies error handling.
If you are going to batch test servers/URLs for their headers, you might
take a look at wget2. It has a statistics output for each URL/server
including number of links (with max-redirect it would be 0 or 1).
Looks for '--stats-site' at
https://gnuwget.gitlab.io/wget2/reference/md_wget2.html.
If you are able to read/write C code, fork/download the project from
Gitlab and check the examples/.
