What does mean Stateless in Asp.Net?

A stateless protocol is characterized by the absence of a connection or relationship between consecutive request-response pairs. In this type of protocol, the server treats each request as an independent entity and does not maintain any session-specific information for the client. An example of a stateless protocol is HTTP, where the server does not retain any knowledge of variable values used in previous requests.

In a purely stateless environment, a session ID would not be necessary as all the information required for processing would be included in each request. However, many applications require session state to maintain user authentication, track user activities, or store variable values. In ASP.NET, session state allows for the identification of requests originating from the same browser within a specific timeframe, creating a session. It provides a mechanism to persist variable values throughout the duration of that session. On the other hand, ASP.NET-MVC, being a model-view-controller framework, does not rely on server-side controls and does not maintain state in the same way. The MVC architecture separates the application into distinct components, allowing for streamlined data delivery to the client.


A stateful environment retains memory of past interactions, meaning that previous transactions are remembered and may impact the current transaction.
