Hi I am playing with server implementation for Gemini and I bumped into one case where I feel the behavior is not strictly specified so I would appreciate your help and clarification on it:
Link in Gemini document can be relative link but how is actually defined behavior for relative link `../`? I have instinctively expected that it would work like `cd ..` on Linux but I have experienced that many clients treat it as "Back" button in classical browser - e.g. takes you to the previously visited page. What is the "correct"/expected/specified behavior for this case?
Thanks for your help
It's really strange that a ../ link behaves like a back button, you maywant to report that to the authors of your clients; `..' should take you"up" one level[0].
That said, if you're writing a server don't forget to clean the path youreceive, because a client could send a request with one or more.. component in it.

[0] the URL rfc specifies a cleaning algorithm that removes every .. path component with the preceding non-.. component.
