HTTP is a stateless protocol. Sessions make it stateful. Most applications need to keep track of certain state of a particular user. This could be the contents of a shopping basket or the user id of the currently Assignment 2 unit 302 in user.

Without the idea of sessions, the user would have to identify, and probably authenticate, on every request. Rails will create a new session automatically if a new user accesses the application. It will load an existing session if the user has already used the application. A session usually consists of a hash of values and a session ID, usually a character string, to identify the hash.

Every cookie sent to the client's browser includes the session ID. And the other way round: In Rails you can save and retrieve values using the session method: The session ID is generated using SecureRandom. Currently it is not feasible to brute-force Rails' session IDs.

Many web applications have an authentication system: From now on, the session is valid. On every request the application will load the user, identified by the user id in the session, without the need for new authentication.

The session ID in the cookie identifies the session. Hence, the cookie serves as temporary authentication for the web application. Anyone who seizes a cookie from someone else, may use the web application as this user - with possibly severe consequences.

Here are some ways to hijack a session, and their countermeasures: Sniff the cookie in an insecure network. A wireless LAN can be an example of such a network.

In an unencrypted wireless LAN, it is especially easy to listen to the traffic of all connected clients. For the web application builder this means to provide a secure connection over SSL.

So if the last user didn't log out of a web application, you would be able to use it as this user. Provide the user with a log-out button in the web application, and make it prominent.


Many cross-site scripting XSS exploits aim at obtaining the user's cookie. You'll read more about XSS later. Instead of stealing a cookie unknown to the attacker, they fix a user's session identifier in the cookie known to them. Read more about this so-called session fixation later.

The main objective of most attackers is to make money. Do not store large objects in a session. Instead you should store them in the database and save their id in the session.

This will eliminate synchronization headaches and it won't fill up your session storage space depending on what session storage you chose, see below.

This will also be a good idea, if you modify the structure of an object and old versions of it are still in some user's cookies. With server-side session storages you can clear out the sessions, but with client-side storages, this is hard to mitigate.

Critical data should not be stored in session. If the user clears their cookies or closes the browser, they will be lost. And with a client-side session storage, the user can read the data.

The most important is ActionDispatch:: The CookieStore saves the session hash directly in a cookie on the client-side. The server retrieves the session hash from the cookie and eliminates the need for a session ID. That will greatly increase the speed of the application, but it is a controversial storage option and you have to think about the security implications and storage limitations of it: Cookies imply a strict size limit of 4kB.

This is fine as you should not store large amounts of data in a session anyway, as described before.Turnitin provides instructors with the tools to prevent plagiarism, engage students in the writing process, and provide personalized feedback.
