In ASP.NET, a session is a server-side storage that enables you to store and retrieve values for a user as they navigate your website. It is commonly used to store user-specific data, such as shopping cart contents, login information, or user preferences. To check if a session exists, you can use the Session[“key”] syntax, where “key” is the name of the session variable you want to check. If the session variable exists, it will return the value of the variable. If it does not exist, it will return null.

Using sessions in ASP.NET offers several benefits. First, it provides a way to store user-specific data that can be accessed across multiple pages. This eliminates the need to pass data through query strings or hidden fields, which can be cumbersome and insecure.

For example, you can use sessions to track the products a user has viewed or added to their shopping cart, and then use this information to make recommendations or offer discounts.
