Good to know... I took a different approach with an unknown second digit as
you saw. I went back and re-read the spec... I couldn't find clear guidance
either way. In my mind it was better to be strict so that unknown status
codes wouldn't result in something unintended. To me a 29 isn't a 20... but
the spec does say that clients can exist without knowledge of the second
digit in a status code... I'll have to think about this some more.

Humm... the CLI version (that uses the same library) didn't fail on that
link. I think the intent is to get a directory listing of the content
inside the zip file, right? I'll have to walk through the code specifically
for that to see where it went wrong. Thanks for writing those tests.

Mime--types... yeah. I'll add that in.

True. The client code underneath the HTTP handler always sends a
certificate when it makes the Gemini call. It's the same certificate for
every call, so there's nothing leaking from the users browser into the
certificate. Was that the concern?

Thanks for your feedback!
