[Feature Request] Accept session ID in server URL

[msujew]

With #92, users can specify a specific server to use for the collaboration session by prefixing the session ID with the URL and a #. It would be good to offer a page in the server that allows to redirect to an IDE using that session ID if the user accidentally pastes the URL in the browser.

This would require a GET handler for /, right? It would be good to have one anyway – if no fragment is given, it should redirect to a URL previously configured for the server (for our public instance, that would be www.open-collab.tools), or alternatively return some infos about the server in JSON format.

But how do we know to which IDE to redirect with a room ID?

Yes

But how do we know to which IDE to redirect with a room ID?

We could offer a page that offers multiple redirects:

1. To playground/online IDE
2. VS Code
3. IntelliJ?

The server might actually not host this page directly, but redirect to a specific page of the www page, but retaining the #<sessionId> fragment.
