What type of cookie is typically implemented to enhance the user experience without storing it permanently?

A session cookie is designed specifically to enhance the user experience during a single session on a website without retaining data once the session ends. These cookies are temporary and are used to remember user actions, preferences, and authentication state while the user navigates through a site. For example, if a user logs into a website, the session cookie allows the site to remember that the user is logged in as they move from page to page. Once the user closes their browser or ends the session, these cookies are deleted, thus not storing any information permanently.

In contrast, other types of cookies serve different purposes. Authentication cookies persist beyond a single session, allowing users to remain logged in between visits. Persistent cookies are intended to be stored on a user's device for a longer period, facilitating features like remembering login information and user preferences across multiple sessions. Tracking cookies collect data over time to track user behavior and activity across websites, which can raise privacy concerns. Thus, session cookies are the appropriate choice for enhancing user experience on a temporary basis without any permanent storage.
