Now add the below line of code to add Session above the builder.Build() function. Cached items are stored by the app instance on the server where the app is running. The Distributed Memory Cache isn’t an actual distributed cache. The functionality of the above line of code is that it creates a default implementation of IDistributedCache. Go to the IServices collection and add the below line of code before the builder.Build() function:ī圜ache() For that, navigate to the Program.cs file in the project.ĭon’t forget to check out: Startup.cs Missing in. Now, to enable session in our Asp.net Core MVC web application we need to do some configuration. You can use session end event in global.I will create an Asp.net Core 6 MVC web application by the name “SessionDemo”.īelow is the screenshot of the project folder structure. Sometimes you may need functionality like Logout and Logout Completely, means you can provide some message after user click logout link, you can tell them they can still login back again (without asking for login credential) or logout completely. Usually we set the particular session key to null ( Session = null ), so we know wherever we have checked that particular session key value, will surely fail. Session.Abandon(), will cancel the current session Session.Clear() method will remove all keys and values from the current session There are different ways we can kill the current session. We also can also disable the session completely, that will surely increase the performance of the application. SessionState mode is specified in web.config, default mode is "InProc", you can also change the time duration. We also can specify custom storage option for session.Session data is stored in the SQL Server Database, we can maintain the session data even when application process restarted.In this mode all session data stored in separate memory called the ASP.NET Service, we can maintain the session data even when application process restarted.This is default Session State modes, in this mode session data gets stored in memory on the web server.You can access session object in your razor view directly this way _uobj = Session as UserObject Now assume user on mydashboard page, where we want to show a welcome message to user, now we can get the information from session object, we don't need to make any database call. In the below example, a string value is set in the Session object in Controller and it is then displayed in View.Ĭontroller public class FirstController : Controller Session is available across multiple requests. Session is used for passing value from Controller to View and also from one Controller to another. While retrieving, the data it needs to be Type Casted to its original type as the data is stored as objects and it also requires NULL checks while retrieving. Keys and Values where Keys are String while Values will be objects. Session saves data similar to a Dictionary object i.e. State Management across requests in ASP.Net MVC Razor. Session is derived from the HttpSessionStateBase class and is used for persisting data i.e. Session is a temporary memory location where we can hold small amount of data for a certain period of time during user visit on any website, Session is a HttpSessionStateBase object. The Server does not have knowledge about the variable values, which are being used in the previous request Every HTTP request is treated as an independent request. Web applications work on HTTP protocol and HTTP is a stateless protocol.
