        response.writeHead(200, {'content-type':'text/json'})
        response.end(JSON.stringify(some_array.slice(1, 10))) //send elements 1 to 10
    } else {
        // handle sync request (by server index.html)
        if (request.url == '/') {
            response.writeHead(200, {'content-type': 'text/html'})
            util.pump(fs.createReadStream('index.html'), response)
        } 
        else 
        {
            // 404 error
        }
    }
