-## Installation
-
-This is a [Node.js](https://nodejs.org/en/) module available through the
-[npm registry](https://www.npmjs.com/). Installation is done using the
-[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
-
-```sh
-$ npm install express-session
-```
-
-## API
-
-```js
-var session = require('express-session')
-```
-
-### session(options)
-
-Create a session middleware with the given `options`.
-
-**Note** Session data is _not_ saved in the cookie itself, just the session ID.
-Session data is stored server-side.
-
-**Note** Since version 1.5.0, the [`cookie-parser` middleware](https://www.npmjs.com/package/cookie-parser)
-no longer needs to be used for this module to work. This module now directly reads
-and writes cookies on `req`/`res`. Using `cookie-parser` may result in issues
-if the `secret` is not the same between this module and `cookie-parser`.
-
-**Warning** The default server-side session storage, `MemoryStore`, is _purposely_
-not designed for a production environment. It will leak memory under most
-conditions, does not scale past a single process, and is meant for debugging and
-developing.
-
-For a list of stores, see [compatible session stores](#compatible-session-stores).
-
-#### Options
-
-`express-session` accepts these properties in the options object.
-
-##### cookie
-
-Settings object for the session ID cookie. The default value is
-`{ path: '/', httpOnly: true, secure: false, maxAge: null }`.
-
-In addition to providing a static object, you can also pass a callback function to dynamically generate the cookie options for each request. The callback receives the `req` object as its argument and should return an object containing the cookie settings.
-
-```js
-var app = express()
-app.use(session({
-  secret: 'keyboard cat',
-  resave: false,
-  saveUninitialized: true,
-  cookie: function(req) {
-    var match = req.url.match(/^\/([^/]+)/);
-    return {
-      path: match ? '/' + match[1] : '/',
-      httpOnly: true,
-      secure: req.secure || false,
-      maxAge: 60000
-    }
-  }
-}))
-```
-
-The following are options that can be set in this object.
-
-##### cookie.domain
-
-Specifies the value for the `Domain` `Set-Cookie` attribute. By default, no domain
-is set, and most clients will consider the cookie to apply to only the current
-domain.
-
-##### cookie.expires
-
-Specifies the `Date` object to be the value for the `Expires` `Set-Cookie` attribute.
-By default, no expiration is set, and most clients will consider this a
-"non-persistent cookie" and will delete it on a condition like exiting a web browser
-application.
-
-**Note** If both `expires` and `maxAge` are set in the options, then the last one
-defined in the object is what is used.
-
-**Note** The `expires` option should not be set directly; instead only use the `maxAge`
-option.
-
-##### cookie.httpOnly
-
-Specifies the `boolean` value for the `HttpOnly` `Set-Cookie` attribute. When truthy,
-the `HttpOnly` attribute is set, otherwise it is not. By default, the `HttpOnly`
-attribute is set.
-
-**Note** be careful when setting this to `true`, as compliant clients will not allow
-client-side JavaScript to see the cookie in `document.cookie`.
-
-##### cookie.maxAge
-
-Specifies the `number` (in milliseconds) to use when calculating the `Expires`
-`Set-Cookie` attribute. This is done by taking the current server time and adding
-`maxAge` milliseconds to the value to calculate an `Expires` datetime. By default,
-no maximum age is set.
-
-**Note** If both `expires` and `maxAge` are set in the options, then the last one
-defined in the object is what is used.
-
-##### cookie.partitioned
-
-Specifies the `boolean` value for the [`Partitioned` `Set-Cookie`](rfc-cutler-httpbis-partitioned-cookies)
-attribute. When truthy, the `Partitioned` attribute is set, otherwise it is not.
-By default, the `Partitioned` attribute is not set.
-
-**Note** This is an attribute that has not yet been fully standardized, and may
-change in the future. This also means many clients may ignore this attribute until
-they understand it.
-
-More information about can be found in [the proposal](https://github.com/privacycg/CHIPS).
-
-##### cookie.path
-
-Specifies the value for the `Path` `Set-Cookie`. By default, this is set to `'/'`, which
-is the root path of the domain.
-
-##### cookie.priority
-
-Specifies the `string` to be the value for the [`Priority` `Set-Cookie` attribute][rfc-west-cookie-priority-00-4.1].
-
-  - `'low'` will set the `Priority` attribute to `Low`.
-  - `'medium'` will set the `Priority` attribute to `Medium`, the default priority when not set.
-  - `'high'` will set the `Priority` attribute to `High`.
-
-More information about the different priority levels can be found in
-[the specification][rfc-west-cookie-priority-00-4.1].
-
-**Note** This is an attribute that has not yet been fully standardized, and may change in the future.
-This also means many clients may ignore this attribute until they understand it.
-
-##### cookie.sameSite
-
-Specifies the `boolean` or `string` to be the value for the `SameSite` `Set-Cookie` attribute.
-By default, this is `false`.
-
-  - `true` will set the `SameSite` attribute to `Strict` for strict same site enforcement.
-  - `false` will not set the `SameSite` attribute.
-  - `'lax'` will set the `SameSite` attribute to `Lax` for lax same site enforcement.
-  - `'none'` will set the `SameSite` attribute to `None` for an explicit cross-site cookie.
-  - `'strict'` will set the `SameSite` attribute to `Strict` for strict same site enforcement.
-  - `'auto'` will set the `SameSite` attribute to `None` for secure connections and `Lax` for non-secure connections.
-
-More information about the different enforcement levels can be found in
-[the specification][rfc-6265bis-03-4.1.2.7].
-
-**Note** This is an attribute that has not yet been fully standardized, and may change in
-the future. This also means many clients may ignore this attribute until they understand it.
-
-**Note** There is a [draft spec](https://tools.ietf.org/html/draft-west-cookie-incrementalism-01)
-that requires that the `Secure` attribute be set to `true` when the `SameSite` attribute has been
-set to `'none'`. Some web browsers or other clients may be adopting this specification.
-
-The `cookie.sameSite` option can also be set to the special value `'auto'` to have
-this setting automatically match the determined security of the connection. When the connection
-is secure (HTTPS), the `SameSite` attribute will be set to `None` to enable cross-site usage.
-When the connection is not secure (HTTP), the `SameSite` attribute will be set to `Lax` for
-better security while maintaining functionality. This is useful when the Express `"trust proxy"`
-setting is properly setup to simplify development vs production configuration, particularly
-for SAML authentication scenarios.
-
-##### cookie.secure
-
-Specifies the `boolean` value for the `Secure` `Set-Cookie` attribute. When truthy,
-the `Secure` attribute is set, otherwise it is not. By default, the `Secure`
-attribute is not set.
-
-**Note** be careful when setting this to `true`, as compliant clients will not send
-the cookie back to the server in the future if the browser does not have an HTTPS
-connection.
-
-Please note that `secure: true` is a **recommended** option. However, it requires
-an https-enabled website, i.e., HTTPS is necessary for secure cookies. If `secure`
-is set, and you access your site over HTTP, the cookie will not be set. If you
-have your node.js behind a proxy and are using `secure: true`, you need to set
-"trust proxy" in express:
-
-```js
-var app = express()
-app.set('trust proxy', 1) // trust first proxy
-app.use(session({
-  secret: 'keyboard cat',
-  resave: false,
-  saveUninitialized: true,
-  cookie: { secure: true }
-}))
-```
-
-For using secure cookies in production, but allowing for testing in development,
-the following is an example of enabling this setup based on `NODE_ENV` in express:
-
-```js
-var app = express()
-var sess = {
-  secret: 'keyboard cat',
-  cookie: {}
-}
-
-if (app.get('env') === 'production') {
-  app.set('trust proxy', 1) // trust first proxy
-  sess.cookie.secure = true // serve secure cookies
-}
-
-app.use(session(sess))
-```
-
-The `cookie.secure` option can also be set to the special value `'auto'` to have
-this setting automatically match the determined security of the connection. Be
-careful when using this setting if the site is available both as HTTP and HTTPS,
-as once the cookie is set on HTTPS, it will no longer be visible over HTTP. This
-is useful when the Express `"trust proxy"` setting is properly setup to simplify
-development vs production configuration.
-
-##### genid
-
-Function to call to generate a new session ID. Provide a function that returns
-a string that will be used as a session ID. The function is given `req` as the
-first argument if you want to use some value attached to `req` when generating
-the ID.
-
-The default value is a function which uses the `uid-safe` library to generate IDs.
-
-**NOTE** be careful to generate unique IDs so your sessions do not conflict.
-
-```js
-app.use(session({
-  genid: function(req) {
-    return genuuid() // use UUIDs for session IDs
-  },
-  secret: 'keyboard cat'
-}))
-```
-
-##### name
-
-The name of the session ID cookie to set in the response (and read from in the
-request).
-
-The default value is `'connect.sid'`.
-
-**Note** if you have multiple apps running on the same hostname (this is just
-the name, i.e. `localhost` or `127.0.0.1`; different schemes and ports do not
-name a different hostname), then you need to separate the session cookies from
-each other. The simplest method is to simply set different `name`s per app.
-
-##### proxy
-
-Trust the reverse proxy when setting secure cookies (via the "X-Forwarded-Proto"
-header).
-
-The default value is `undefined`.
-
-  - `true` The "X-Forwarded-Proto" header will be used.
-  - `false` All headers are ignored and the connection is considered secure only
-    if there is a direct TLS/SSL connection.
-  - `undefined` Uses the "trust proxy" setting from express
-
-##### resave
-
-Forces the session to be saved back to the session store, even if the session
-was never modified during the request. Depending on your store this may be
-necessary, but it can also create race conditions where a client makes two
-parallel requests to your server and changes made to the session in one
-request may get overwritten when the other request ends, even if it made no
-changes (this behavior also depends on what store you're using).
-
-The default value is `true`, but using the default has been deprecated,
-as the default will change in the future. Please research into this setting
-and choose what is appropriate to your use-case. Typically, you'll want
-`false`.
-
-How do I know if this is necessary for my store? The best way to know is to
-check with your store if it implements the `touch` method. If it does, then
-you can safely set `resave: false`. If it does not implement the `touch`
-method and your store sets an expiration date on stored sessions, then you
-likely need `resave: true`.
-
-##### rolling
-
-Force the session identifier cookie to be set on every response. The expiration
-is reset to the original [`maxAge`](#cookiemaxage), resetting the expiration
-countdown.
-
-The default value is `false`.
-
-With this enabled, the session identifier cookie will expire in
-[`maxAge`](#cookiemaxage) since the last response was sent instead of in
-[`maxAge`](#cookiemaxage) since the session was last modified by the server.
-
-This is typically used in conjunction with short, non-session-length
-[`maxAge`](#cookiemaxage) values to provide a quick timeout of the session data
-with reduced potential of it occurring during on going server interactions.
-
-**Note** When this option is set to `true` but the `saveUninitialized` option is
-set to `false`, the cookie will not be set on a response with an uninitialized
-session. This option only modifies the behavior when an existing session was
-loaded for the request.
-
-##### saveUninitialized
-
-Forces a session that is "uninitialized" to be saved to the store. A session is
-uninitialized when it is new but not modified. Choosing `false` is useful for
-implementing login sessions, reducing server storage usage, or complying with
-laws that require permission before setting a cookie. Choosing `false` will also
-help with race conditions where a client makes multiple parallel requests
-without a session.
-
-The default value is `true`, but using the default has been deprecated, as the
-default will change in the future. Please research into this setting and
-choose what is appropriate to your use-case.
-
-**Note** if you are using Session in conjunction with PassportJS, Passport
-will add an empty Passport object to the session for use after a user is
-authenticated, which will be treated as a modification to the session, causing
-it to be saved. *This has been fixed in PassportJS 0.3.0*
-
-##### secret
-
-**Required option**
-
-This is the secret used to sign the session ID cookie. The secret can be any type
-of value that is supported by Node.js `crypto.createHmac` (like a string or a
-`Buffer`). This can be either a single secret, or an array of multiple secrets. If
-an array of secrets is provided, only the first element will be used to sign the
-session ID cookie, while all the elements will be considered when verifying the
-signature in requests. The secret itself should be not easily parsed by a human and
-would best be a random set of characters. A best practice may include:
-
-  - The use of environment variables to store the secret, ensuring the secret itself
-    does not exist in your repository.
-  - Periodic updates of the secret, while ensuring the previous secret is in the
-    array.
-
-Using a secret that cannot be guessed will reduce the ability to hijack a session to
-only guessing the session ID (as determined by the `genid` option).
-
-Changing the secret value will invalidate all existing sessions. In order to rotate
-the secret without invalidating sessions, provide an array of secrets, with the new
-secret as first element of the array, and including previous secrets as the later
-elements.
-
-**Note** HMAC-256 is used to sign the session ID. For this reason, the secret should
-contain at least 32 bytes of entropy.
-
-##### store
-
-The session store instance, defaults to a new `MemoryStore` instance.
-
-##### unset
-
-Control the result of unsetting `req.session` (through `delete`, setting to `null`,
-etc.).
-
-The default value is `'keep'`.
-
-  - `'destroy'` The session will be destroyed (deleted) when the response ends.
-  - `'keep'` The session in the store will be kept, but modifications made during
-    the request are ignored and not saved.
-
-### 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:
-
-```js
-// Use the session middleware
-app.use(session({ secret: 'keyboard cat', cookie: { maxAge: 60000 }}))
-
-// Access the session as req.session
-app.get('/', function(req, res, next) {
-  if (req.session.views) {
-    req.session.views++
-    res.setHeader('Content-Type', 'text/html')
-    res.write('<p>views: ' + req.session.views + '</p>')
-    res.write('<p>expires in: ' + (req.session.cookie.maxAge / 1000) + 's</p>')
-    res.end()
-  } else {
-    req.session.views = 1
-    res.end('welcome to the session demo. refresh!')
-  }
-})
-```
-
-#### Session.regenerate(callback)
-
-To regenerate the session simply invoke the method. Once complete,
-a new SID and `Session` instance will be initialized at `req.session`
-and the `callback` will be invoked.
-
-```js
-req.session.regenerate(function(err) {
-  // will have a new session here
-})
-```
-
-#### Session.destroy(callback)
-
-Destroys the session and will unset the `req.session` property.
-Once complete, the `callback` will be invoked.
-
-```js
-req.session.destroy(function(err) {
-  // cannot access session here
-})
-```
-
-#### Session.reload(callback)
-
-Reloads the session data from the store and re-populates the
-`req.session` object. Once complete, the `callback` will be invoked.
-
-```js
-req.session.reload(function(err) {
-  // session updated
-})
-```
-
-#### Session.save(callback)
-
-Save the session back to the store, replacing the contents on the store with the
-contents in memory (though a store may do something else--consult the store's
-documentation for exact behavior).
-
-This method is automatically called at the end of the HTTP response if the
-session data has been altered (though this behavior can be altered with various
-options in the middleware constructor). Because of this, typically this method
-does not need to be called.
-
-There are some cases where it is useful to call this method, for example,
-redirects, long-lived requests or in WebSockets.
-
-```js
-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.
-
-### req.session.id
-
-Each session has a unique ID associated with it. This property is an
-alias of [`req.sessionID`](#reqsessionid-1) and cannot be modified.
-It has been added to make the session ID accessible from the `session`
-object.
-
-### req.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.
-
-#### Cookie.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
-
-```js
-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.cookie.maxAge` to its original value.
-
-```js
-req.session.cookie.maxAge // => 30000
-```
-
-#### Cookie.originalMaxAge
-
-The `req.session.cookie.originalMaxAge` property returns the original
-`maxAge` (time-to-live), in milliseconds, of the session cookie.
-
-### req.sessionID
-
-To get the ID of the loaded session, access the request property
-`req.sessionID`. This is simply a read-only value set when a session
-is loaded/created.
-
-## Session Store Implementation
-
-Every session store _must_ be an `EventEmitter` and implement specific
-methods. The following methods are the list of **required**, **recommended**,
-and **optional**.
-
-  * Required methods are ones that this module will always call on the store.
-  * Recommended methods are ones that this module will call on the store if
-    available.
-  * Optional methods are ones this module does not call at all, but helps
-    present uniform stores to users.
-
-For an example implementation view the [connect-redis](http://github.com/visionmedia/connect-redis) repo.
-
-### store.all(callback)
-
-**Optional**
-
-This optional method is used to get all sessions in the store as an array. The
-`callback` should be called as `callback(error, sessions)`.
-
-### store.destroy(sid, callback)
-
-**Required**
-
-This required method is used to destroy/delete a session from the store given
-a session ID (`sid`). The `callback` should be called as `callback(error)` once
-the session is destroyed.
-
-### store.clear(callback)
-
-**Optional**
-
-This optional method is used to delete all sessions from the store. The
-`callback` should be called as `callback(error)` once the store is cleared.
-
-### store.length(callback)
-
-**Optional**
-
-This optional method is used to get the count of all sessions in the store.
-The `callback` should be called as `callback(error, len)`.
-
-### store.get(sid, callback)
-
-**Required**
-
-This required method is used to get a session from the store given a session
-ID (`sid`). The `callback` should be called as `callback(error, session)`.
-
-The `session` argument should be a session if found, otherwise `null` or
-`undefined` if the session was not found (and there was no error). A special
-case is made when `error.code === 'ENOENT'` to act like `callback(null, null)`.
-
-### store.set(sid, session, callback)
-
-**Required**
-
-This required method is used to upsert a session into the store given a
-session ID (`sid`) and session (`session`) object. The callback should be
-called as `callback(error)` once the session has been set in the store.
-
-### store.touch(sid, session, callback)
-
-**Recommended**
-
-This recommended method is used to "touch" a given session given a
-session ID (`sid`) and session (`session`) object. The `callback` should be
-called as `callback(error)` once the session has been touched.
-
-This is primarily used when the store will automatically delete idle sessions
-and this method is used to signal to the store the given session is active,
-potentially resetting the idle timer.

-## Examples
-
-### View counter
-
-A simple example using `express-session` to store page views for a user.
-
-```js
-var express = require('express')
-var parseurl = require('parseurl')
-var session = require('express-session')
-
-var app = express()
-
-app.use(session({
-  secret: 'keyboard cat',
-  resave: false,
-  saveUninitialized: true
-}))
-
-app.use(function (req, res, next) {
-  if (!req.session.views) {
-    req.session.views = {}
-  }
-
-  // get the url pathname
-  var pathname = parseurl(req).pathname
-
-  // count the views
-  req.session.views[pathname] = (req.session.views[pathname] || 0) + 1
-
-  next()
-})
-
-app.get('/foo', function (req, res, next) {
-  res.send('you viewed this page ' + req.session.views['/foo'] + ' times')
-})
-
-app.get('/bar', function (req, res, next) {
-  res.send('you viewed this page ' + req.session.views['/bar'] + ' times')
-})
-
-app.listen(3000)
-```
-
-### User login
-
-A simple example using `express-session` to keep a user log in session.
-
-```js
-var escapeHtml = require('escape-html')
-var express = require('express')
-var session = require('express-session')
-
-var app = express()
-
-app.use(session({
-  secret: 'keyboard cat',

-  // this is only called when there is an authentication user due to isAuthenticated
-  res.send('hello, ' + escapeHtml(req.session.user) + '!' +
-    ' <a href="/logout">Logout</a>')
-})
-
-app.get('/', function (req, res) {
-  res.send('<form action="/login" method="post">' +
-    'Username: <input name="user"><br>' +
-    'Password: <input name="pass" type="password"><br>' +
-    '<input type="submit" text="Login"></form>')
-})
-
-app.post('/login', express.urlencoded({ extended: false }), function (req, res) {
-  // login logic to validate req.body.user and req.body.pass
-  // would be implemented here. for this example any combo works
-
-  // regenerate the session, which is good practice to help
-  // guard against forms of session fixation
-  req.session.regenerate(function (err) {
-    if (err) next(err)
-
-    // store user information in session, typically a user id
-    req.session.user = req.body.user
-
-    // save the session before redirection to ensure page
-    // load does not happen before session is saved
-    req.session.save(function (err) {
-      if (err) return next(err)
-      res.redirect('/')
-    })
-  })
-})
-
-app.get('/logout', function (req, res, next) {
-  // logout logic
-
-  // clear the user from the session object and save.
-  // this will ensure that re-using the old session id
-  // does not have a logged in user
-  req.session.user = null
-  req.session.save(function (err) {
-    if (err) next(err)
-
-    // regenerate the session, which is good practice to help

-      res.redirect('/')
-    })
-  })
-})
-
-app.listen(3000)
-```
-
-## Debugging
-
-This module uses the [debug](https://www.npmjs.com/package/debug) module
-internally to log information about session operations.
-
-To see all the internal logs, set the `DEBUG` environment variable to
-`express-session` when launching your app (`npm start`, in this example):
-
-```sh
-$ DEBUG=express-session npm start
-```
-
-On Windows, use the corresponding command;
-
-```sh
-> set DEBUG=express-session & npm start
-```
