Istuntoevästeen, also known as a session cookie, is a small piece of data that a website stores on a user's computer for the duration of their visit. Unlike persistent cookies, which remain on a user's device for a set period, session cookies are temporary and are automatically deleted when the user closes their web browser.

The primary purpose of a session cookie is to maintain state information for a user as they navigate a website. For example, when a user logs into a website, a session cookie can be used to remember their login status, allowing them to access different pages without having to re-enter their credentials. Similarly, in e-commerce, session cookies can track items added to a shopping cart as a user browses different products.

Session cookies are crucial for providing a seamless and personalized user experience. They enable websites to remember user preferences, choices, and activities during a single browsing session. Without them, websites would have to treat each page request as a completely new interaction, making functionalities like online shopping or user authentication impossible.

The data stored in session cookies is typically temporary and not intended for long-term tracking. Once the browser is closed, the information is lost. This ephemeral nature makes them a privacy-friendly option compared to persistent cookies, which can be used to track user behavior across multiple sessions and over extended periods. Websites often use session cookies to manage user sessions and enhance website functionality.
