Sessioevästeitä

Sessioevästeitä, also known as session cookies, are temporary data files that websites store on a user's device while they are actively browsing a particular site. Unlike persistent cookies that remain on a device for a set period, session cookies are automatically deleted once the user closes their web browser or finishes their session on the website. Their primary purpose is to maintain the user's state and facilitate navigation throughout their visit.

These cookies are essential for many website functionalities. For instance, they are commonly used to keep track of items in a user's shopping cart on e-commerce sites. Without session cookies, items would disappear from the cart every time a user navigated to a different page. They also play a crucial role in managing user logins, allowing users to remain authenticated as they move between different sections of a website without needing to re-enter their credentials repeatedly.

Session cookies are generally considered less privacy-invasive than persistent cookies because they are not designed to track user behavior over extended periods or across different websites. They typically store non-personally identifiable information, such as a unique session ID, to link user actions within a single browsing session. While they are a fundamental part of modern web functionality, users can typically manage their browser settings to block or delete all cookies, including session cookies, though this may affect the user experience on many websites.
