Advantages and Disadvantages of Session in asp.net.

Following are the basic advantages and disadvantages of session:

Advantages:

• It stores user states and data to all over the application.
• Easy mechanism to implement and we can store any kind of object.
• Stores every user data separately.
• Session is secure and transparent from user because session object is stored on the server.

Disadvantages:

• Performance overhead in case of large number of user, because of session data stored in server memory.
• Overhead involved in serializing and De-Serializing session Data. Because In case of StateServer and SQLServer session mode we need to serialize the object before store.
