@oschwartz10612 commented on GitHub (Jan 20, 2026):

If you remove the following and just use the header: value format does
it work?

HTTP/1.1 301 Moved Permanently

so it should look like:

Location: https://dom.tld
Content-Type: text/html
Connection: close

It does save the custom header contents at least, although doesn't function as expected… the resulting target is "https://dom.tld/*" rather than "https://dom.tld", resulting in a 404 from the target server

Well, I've moved on, so will leave this issue to remain, since it appears it will be closed anyway…
