I believe 90% of my coworkers and former coworkers would be unable to answer the HTTP response question.
And 95% haven't used netcat or wireshark. I wouldn't have either, if it wasn't for some particular work related to messaging.
They're able to develop reasonable line of business websites in spite of that.
I would be extremely worried if they were unable to answer about the difference between GET or POST, or the difference between statically and dynamically typed languages, so I agree with those.
I basically lived in Wire shark for a couple of years working for a voip company and still use stuff like curl all the time and I don't think I could walk through an http request of the top of my head.
GET / HTTP/1.1\r\n and some kind of sensible response is not too much to expect someone to know. HTTP is super easy and I see the HTTP transaction test as "did you ever get curious as to how exactly a core part of the current Internet actually works". I'm sure that there are app developers out there who can spin crud stuff all day and have no idea about this, just as there are curious people who couldn't stand up todomvc to save their life, but in general, all of the most talented people I've worked with knew their stuff front to back, and had at least a few areas of expertise.
CGI is also cool to learn about the workings of, since it almost seems too simple.

Sure I did.
Then I forgot most of the details because they didn't matter, and I knew I could look them up quickly if I ever needed to write a HTTP client/server for some reason.
Yeah expecting many people to be able write out a complete http request from memory without a reference to look at. But the general structure of a http request is something so basic to web development that asking what the structure of a http request looks like isn't an unreasonable expectation.
Request line (method, uri), header(s), empty, body...
There is some truth to the saying that some people don't have ten years experience, they have two years of experience five times in a row.
Learning to use wireshark or tcpdump is a power tool that does show whether you got more experience in understanding the lower levels, or stayed at requirements-and-tests. (Not necessarily bad, but a good "fork" to jump off from)
