connect-mysql-sessionでのExpressjs

Question

私はexpress-jでconnect-mysql-sessionモジュールを使用しています。 のための私はこれを取得、サーバーへの各要求：

は、なぜそれがこれをやっていますか？

また、リクエストごとに約8個のクッキーが設定されています（connect.sid）。私はそれがasset likje js、cssおよびimagesごとに設定されていると思います。なぜそれは何度も設定されていますか？それは賛成ですか？

HERESに私の設定：

app.set('views', __dirname + '/../views'); 
app.set('view engine', 'html'); 
app.register('.html', require('ejs')); 
app.use(express.bodyParser()); 
app.use(expressValidator); 
app.use(express.methodOverride()); 
app.use(express.cookieParser()); 
app.use(express.session({ 
store: new MySQLSessionStore("test_db", "root", "root"), 
    secret: 'cat' 
})); 
app.use(app.router); 
app.use(express.csrf()); 
app.use(express.static(__dirname + '/../public')); 

よろしく

私はこの約100％わからないんだけど、私はあなたが上に多くの静的なミドルウェアを置くべきだと思います。セッション、クッキー、その他のミドルウェアは不要なので、上記のような静的ミドルウェアを用意することがポイントです。

app.set('views', __dirname + '/../views'); 
app.set('view engine', 'html'); 
app.register('.html', require('ejs')); 
app.use(express.static(__dirname + '/../public')); 
app.use(express.bodyParser()); 
app.use(expressValidator); 
app.use(express.methodOverride()); 
app.use(express.cookieParser()); 
app.use(express.session({ 
store: new MySQLSessionStore("test_db", "root", "root"), 
    secret: 'cat' 
})); 
app.use(app.router); 
app.use(express.csrf());
