/**
* Session:
*
* Setup session store with the given `options`.
*
* Session data is _not_ saved in the cookie itself, however
* cookies are used, so we must use the [cookieParser()](cookieParser.html)
* middleware _before_ `session()`.
*
* Examples:
*
* connect()
* .use(connect.cookieParser())
* .use(connect.session({ secret: 'keyboard cat', key: 'sid', cookie: { secure: true }}))
*
* Options:
*
* - `key` cookie name defaulting to `connect.sid`
* - `store` session store instance
* - `secret` session cookie is signed with this secret to prevent tampering
* - `cookie` session cookie settings, defaulting to `{ path: '/', httpOnly: true, maxAge: null }`
* - `proxy` trust the reverse proxy when setting secure cookies (via "x-forwarded-proto")
*
* Cookie option:
*
* By default `cookie.maxAge` is `null`, meaning no "expires" parameter is set
* so the cookie becomes a browser-session cookie. When the user closes the
* browser the cookie (and session) will be removed.
*
* ## req.session
*
* To store or access session data, simply use the request property `req.session`,
* which is (generally) serialized as JSON by the store, so nested objects
* are typically fine. For example below is a user-specific view counter:
*
* connect()
* .use(connect.favicon())
* .use(connect.cookieParser())
* .use(connect.session({ secret: 'keyboard cat', cookie: { maxAge: 60000 }}))
* .use(function(req, res, next){
* var sess = req.session;
* if (sess.views) {
* res.setHeader('Content-Type', 'text/html');
* res.write('<p>views: ' + sess.views + '</p>');
* res.write('<p>expires in: ' + (sess.cookie.maxAge / 1000) + 's</p>');
* res.end();
* sess.views++;
* } else {
* sess.views = 1;
* res.end('welcome to the session demo. refresh!');
* }
* }
* )).listen(3000);
*
* ## Session#regenerate()
*
* To regenerate the session simply invoke the method, once complete
* a new SID and `Session` instance will be initialized at `req.session`.
*
* req.session.regenerate(function(err){
* // will have a new session here
* });
*
* ## Session#destroy()
*
* Destroys the session, removing `req.session`, will be re-generated next request.
*
* req.session.destroy(function(err){
* // cannot access session here
* });
*
* ## Session#reload()
*
* Reloads the session data.
*
* req.session.reload(function(err){
* // session updated
* });
*
* ## Session#save()
*
* Save the session.
*
* req.session.save(function(err){
* // session saved
* });
*
* ## Session#touch()
*
* Updates the `.maxAge` property. Typically this is
* not necessary to call, as the session middleware does this for you.
*
* ## Session#cookie
*
* Each session has a unique cookie object accompany it. This allows
* you to alter the session cookie per visitor. For example we can
* set `req.session.cookie.expires` to `false` to enable the cookie
* to remain for only the duration of the user-agent.
*
* ## Session#maxAge
*
* Alternatively `req.session.cookie.maxAge` will return the time
* remaining in milliseconds, which we may also re-assign a new value
* to adjust the `.expires` property appropriately. The following
* are essentially equivalent
*
* var hour = 3600000;
* req.session.cookie.expires = new Date(Date.now() + hour);
* req.session.cookie.maxAge = hour;
*
* For example when `maxAge` is set to `60000` (one minute), and 30 seconds
* has elapsed it will return `30000` until the current request has completed,
* at which time `req.session.touch()` is called to reset `req.session.maxAge`
* to its original value.
*
* req.session.cookie.maxAge;
* // => 30000
*
* Session Store Implementation:
*
* Every session store _must_ implement the following methods
*
* - `.get(sid, callback)`
* - `.set(sid, session, callback)`
* - `.destroy(sid, callback)`
*
* Recommended methods include, but are not limited to:
*
* - `.length(callback)`
* - `.clear(callback)`
*
* For an example implementation view the [connect-redis](http://github.com/visionmedia/connect-redis) repo.
