How to make language server read URL if URL is not a file (for example a file inside a ZIP archive)

[LordOfDragons]

I've written a language server for VSCode for a scripting language of mine. I have support in the language server to search and parse files from archive files. I then create URLs in hover information which is not a real file path but something like "delga://path" which the language server would be able to read the file inside an archive file.

This all works inside the language server but not outside.

If for example a user clicks on such a URL I generated in a hover information then VSCode fails to open the file since it tries to open it as a disk file but in truth it is a file from inside an archive.

How can I make it VSCode knows to let the language server intercept opening URLs if it contain a "special" URL only the language server can open and read the content of?
