- Session Cookie: It resides on the client machine for a single session until the user logs out.
- Persistent Cookie: Resides on the user machine for a period specified for its expiry. It may be an hour, a month or never.
In ASP.NET, there are primarily two types of cookies:
- Persistent Cookies: These cookies are stored on the user’s computer even after the session ends. They have an expiration date set and remain valid until that date unless manually deleted by the user or cleared by the application. Persistent cookies are useful for scenarios where you want to remember user preferences or maintain login sessions across multiple visits.
- Session Cookies: These cookies are temporary and are stored only for the duration of the user’s session. Once the user closes the browser or the session expires due to inactivity, session cookies are automatically deleted. They are commonly used to maintain user session state, such as storing session IDs or temporary data during a user’s interaction with the website.
It’s worth noting that ASP.NET provides a convenient way to work with cookies through the HttpCookie class and the Response.Cookies collection for sending cookies to the client, and the Request.Cookies collection for retrieving cookies from the client.
