    <p>I have a simple node.js server testing the connect-redis module as a session store. It all works but I've noticed that I get a new sess: key in redis on every single request. I expected only one key since there is only one session.</p> <p><img src="https://i.stack.imgur.com/40ZZ2.png" alt="redis-cli showing multiple sess: keys"></p> <p>Here's my code :</p> <pre><code>var connect = require('connect'); var util = require("util"); var RedisStore = require("connect-redis")(connect); var http = require('http'); var app = connect() .use(connect.cookieParser('keyboard cat')) .use(connect.query()) .use(connect.session( { secret:"elms", store:new RedisStore({prefix:'sid_'}), cookie:{maxAge:60000, secure:false} })) .use(function(req, res, next) { var sess = req.session; if (sess.views) { res.setHeader('Content-Type', 'text/html'); res.write("&lt;p&gt;" + util.inspect(req.cookies) + "&lt;/p&gt;"); sess.basket = sess.basket || {book1:0, book2:0, book3:0}; if(req.query.buyBook1) {sess.basket.book1 ++;} if(req.query.buyBook2) {sess.basket.book2 ++;} if(req.query.buyBook3) {sess.basket.book3 ++;} if(req.query.expiresession) { sess.cookie.maxAge = 0; } res.write('&lt;p&gt;views: ' + sess.views + '&lt;/p&gt;'); res.write('&lt;ul&gt;\ &lt;li&gt;book1 ' + sess.basket.book1 + ' - &lt;a href="/?buyBook1=true"&gt;Add&lt;/a&gt;&lt;/li&gt;\ &lt;li&gt;book2 ' + sess.basket.book2 + ' - &lt;a href="/?buyBook2=true"&gt;Add&lt;/a&gt;&lt;/li&gt;\ &lt;li&gt;book3 ' + sess.basket.book3 + ' - &lt;a href="/?buyBook3=true"&gt;Add&lt;/a&gt;&lt;/li&gt;\ &lt;/ul&gt;\ &lt;a href="/?expiresession=true"&gt;Expire session&lt;/a&gt;'); res.write('&lt;p&gt;expires in: ' + (sess.cookie.maxAge / 1000) + 's&lt;/p&gt;'); res.write('&lt;p&gt;httpOnly: ' + sess.cookie.httpOnly + '&lt;/p&gt;'); res.write('&lt;p&gt;path: ' + sess.cookie.path + '&lt;/p&gt;'); res.write('&lt;p&gt;domain: ' + sess.cookie.domain + '&lt;/p&gt;'); res.write('&lt;p&gt;secure: ' + sess.cookie.secure + '&lt;/p&gt;'); sess.views ++; } else { sess.views = 1; } res.write("&lt;p&gt;" + util.inspect(req.cookies) + "&lt;/p&gt;"); res.end('welcome to the session demo. refresh!'); }); http.createServer(app).listen(3000); </code></pre> <p>I've noticed that the req.session.cookie.domain is always null. I'm on windows 8 and using the hosts file to map 127.0.0.1 to www.gaz-node.com, which is what I exepected the cookie domain to be at the server. Could be related.</p> <p>Any ideas? Thanks</p>

    1. COYou can easily check if the session is created on the client side. An http only cookie with the name connect.sid should be set, if not you are probably right that your cookie domain is the problem. Chrome dev tools > Ressources > Cookies can help. The browser will refuse to set the session cookie if the domain is not correct.

    2. COhi, yes the cookie is all present and good on the client side, but the domain property is null in node. I'll investigate further into the cookieParser module. I might setup an Ubuntu virtual pc (for the first time) to see if it's an issue with node on windows. Thanks

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
