3. Vibe can't handle GET & POST on the same URL...
we solved this one as well: fortunately (and: of course) vibe can handle this.
what lead us to believe otherwise, was that, unfortunately, one of the handlers crashed (effectively due to a `cast(JSONValue)` of a `Json.Undefined`), without any visible error output; and the only visible error was a "no route matches path" output from vibe.
sorry for the confusion.
