after some investigation, turns out that it *does* in fact respond with a bunch of http headers, but no body, and it does keep the tcp connection alive indefinitely.. curl -v log:
$ curl '

2022-01-22 02:25:15 ERROR 400: Bad Request.
- and that 400 breaks wget's -c , which is bad when combined with -r , eg `wget -r -c
http://127.0.0.1/ - will only work the first time, the 2nd invocation will be broken with a http bad request error. (because hfs doesn't respond with http 416)
