Looks like the culprit here is parse_link from Hypertext. The issue stems from base_url() function of url::ParseOptions that cuts path elements from provided URL, if it doesn't have a trailing slash. This is a intended behavior, as noted in join() function (here).

@ranfdev How we should fix it? Lagrange for example just adds a trailing slash at the end of every URL. We could do that, or add a check in parse_link to know when to add slash.

I've tested the behavior of a simple http server running with python -m http.server, in a folder containing the files

├── subdir
│   ├── index.html
│   └── test.html

Once I try going to localhost/subdir, the python server redirects me to localhost/sudir/, adding a slash.
The slash should be added by the server. Only the server knows if localhost/subdir is a file or a folder.

Even the official gemini documentation does this. You can do, from your terminal

echo "gemini://geminiprotocol.net" | gnutls-cli --tofu -p 1965 geminiprotocol.net

and you'll see a redirect

31 gemini://geminiprotocol.net/

Now, for some reason Geopard doesn't update the URL after the redirect. So the slash doesn't seem to be added. That's a problem we can work on.
