By default, session data is stored for 20 minutes from the last request. So, if you access a page and something is stored as session data for you, it will be automatically removed after 20 minutes unless you have made a new request within this time period.
You can change the timeout duration when setting up sessions for your site see below , but as mentioned, you shouldn't try to use sessions to store data for long periods of time. So, if you are looking to store data between multiple sessions, use cookies - otherwise, the session mechanism is a great choice. To understand the different use cases, think of a classic login system, where the user can check a checkbox to "Stay logged in": If this is not checked, the login state might as well be stored as a session and then disappear when the user leaves the site e.
If it is checked, a cookie should be used instead, resulting in the user still being logged in the next time they start their computer and visit your website. However, discussing sessions vs.
The reason is that while cookies are stored on the device of the user as small, plain-text files , session data is stored temporarily, in memory on the server. However, since your web site will likely have more than one visitor, the server needs to know which visitor a piece of session data belongs to. For this, it creates a session ID, which is stored as a so-called session-cookie on the visitor device. With this ID, the visitor can access their session data across multiple requests.
NET frameworks, Sessions would be available right out of the box. NET Core is much more modular though, allowing you to add the building-blocks you need when you need the. Sessions are one of these building-blocks, so to we'll have to add support for it. This requires two steps:. First, you need to install the Microsoft. Session NuGet package in your project. This article explains ASP. NET sessions in details.
Session is a State Management Technique. A Session can store the value on the Server. It can support any type of object to be stored along with our own custom objects. A session is one of the best techniques for State Management because it stores the data as client-based.
Now to set the session we need to use a config file. We can set the session on one of the following 2 types of configuration files:. NET State service. Now configure with the ASP. NET State Service. Step 1: Go To Start and from there go to "Run" and type "services.
NET State Service and start the service; by default these services are stopped. Step 3: For configuration with web. Generally the state services and web services are not in the same machine of a dedicated server so for the connection we need to write the stateConnectionString and here we need to provide the IP address or the name of the machine where the state service is running and here my services are run on localhost and is the port number.
The ASP. When the client sends a request to the web server, the web server stores the session data on the state server. The StateServer may be the current system or a different system. But it will be totally independent of IIS. The destination of the StateServer will depend on the web. If we set it to localhost then it will store data in the local system itself.
