带反向代理的express.js会话

Question

我已经设置了一个Apache反向代理转发api.mydomain.com到localhost:2000哪个工作正常.

然而,我遇到的真正问题是关于会话 - 似乎在查询时没有存储req.session api.mydomain.com.会议将很好地访问localhost:2000.

我认为这与代理域有关...

server.js

var express = require('express'),
    app = express();

app.enable('trust proxy');

app.configure(function() {
    app.use(express.bodyParser());
    app.use(express.methodOverride());
    app.use(express.cookieParser());
    app.use(express.session({ secret: 'supersecret'});
    app.use(app.router);
});

app.get('/session', function(req, res, next){ 
    console.log(req.session.username)
    // this will be undefined when called from  api.mydomain.com...
});


app.post('/session', function(req, res, next){ 
    req.session.username = 'my username';
});

apache配置

<VirtualHost *:80>
    ServerName api.mydomain.com   
    ProxyPass / http://localhost:2000/
    ProxyPassReverse / http://localhost:2000/

    ProxyPreserveHost On
    ProxyPassReverseCookieDomain api.domain.com localhost:2000
    ProxyPassReverseCookiePath / /
</VirtualHost>

编辑

值得注意的是,进一步测试 - app.use(app.router)在app.configure()... 之前添加以下代码

app.use(function (req, res) {
    res.send('<h2>Hello, your session id is ' + req.sessionID + '</h2>');
});

将导致以下结果(每行代表对应用程序的新GET /会话请求 - 节点尚未重新启动).

本地主机:2000

Hello, your session id is sHkkESxJgzOyDhDwyTjwpNzq
Hello, your session id is sHkkESxJgzOyDhDwyTjwpNzq
Hello, your session id is sHkkESxJgzOyDhDwyTjwpNzq

api.mydomain.com

Hello, your session id is uuo4U5ierZAG8LSH1BdwTlVf
Hello, your session id is 8BxL97Bo35SDt4uliuPgnbia
Hello, your session id is 0xkqZZpzQNvTsQpbJtUlXgkR

设置信息

NodeJS v0.8.8

Apache v2.4.2

ExpressJS v3.0.0rc4

更新2

好吧,到目前为止我已经决定简单使用mydomain.com/api,因为这似乎可以解决所有问题.所以我想这与Apache如何处理与Express的域通信有关!

从Apache ProxyPass 和 Sessions来看，这个 apache 配置也许......

<VirtualHost *:80>
    ServerName api.mydomain.com   
    ProxyPass / http://localhost:2000/
    ProxyPassReverse / http://localhost:2000/
    ProxyPassReverseCookiePath / /
</VirtualHost>
