serving two static folders and connecting to both with websockets

A lot of the youtube and medium resources available on setting serving static folders, and on setting up a websockets server, seem to be using patterns that are not compatible with each other / not harmonious with the latest version of std etc. I have a few stumbling blocks. The first is to serve my 'public' folder to the url, and serve another folder, called 'control', to URL/control, but within the one serve () call. Using a switch statement seems to break everything and I don't really understand why. Eg,

const servePublic = req => staticFiles ('public') ({ 
    request: req, 
    respondWith: r => r 
})

serve (req =>  servePublic (req), { addr: ':80' })

const servePublic = req => staticFiles ('public') ({ 
    request: req, 
    respondWith: r => r 
})

serve (req =>  servePublic (req), { addr: ':80' })

... works, whereas:

// serve public
const servePublic = req => staticFiles ('public') ({ 
    request: req, 
    respondWith: r => r 
})

// serve control
const serveControl = req => staticFiles (`control`) ({ 
    request: req, 
    respondWith: r => r 
})

serve (req => {
    const url = new URL(req.url);
    console.log (url.pathname)

    switch (url.pathname) {
        case `/control`:
            return serveControl (req)
        case `/`:
            return servePublic (req)
    }
}, { addr: ':80' })

// serve public
const servePublic = req => staticFiles ('public') ({ 
    request: req, 
    respondWith: r => r 
})

// serve control
const serveControl = req => staticFiles (`control`) ({ 
    request: req, 
    respondWith: r => r 
})

serve (req => {
    const url = new URL(req.url);
    console.log (url.pathname)

    switch (url.pathname) {
        case `/control`:
            return serveControl (req)
        case `/`:
            return servePublic (req)
    }
}, { addr: ':80' })

... does not. I feel like I am missing something vital.
Then there is websockets - trying to work out how to marry Deno.upgradeWebSocket with this serve pattern. I had gotten them all working on localhost, but Deno Deploy needs for there to be only one listener, I think
