No HTTP version in request

I just found an interesting behavior in Nginx while looking at a reqeust
that was causing an error in my code.

For a request with no HTTP/xx version, Nginx will return no HTTP
response
headers.

From what I gathered, this is just Nginx defaulting to HTTP/0.9, where
no
headers are expected. And actually doing the right thing here.

But shouldn’t $server_protocol default to HTTP/0.9 in that case, instead
of
being an empty string ?

Yes, absence of protocol version is so called HTTP/0.9 but this is adhoc
name, so I think empty string
is correct value, since there is no protocol version at all.
