We should store critical application data in the user’s database and we should cache it in a session only as a performance optimization if required.ĪSP.NET Core maintains the session state by providing a cookie to the client that contains a session ID. It uses a store maintained by the application to persist data across requests from a client. Session state is an ASP.NET Core mechanism to store user data while the user browses the application.

In this section, we have learned how to use cookies in our application. For more information about the APIs and templates provided by ASP.NET Core to support GDPR requirements, visit: General Data Protection Regulation (GDPR) support in ASP.NET Core We should be mindful of the European Union General Data Protection Regulations (GDPR) when issuing cookies and dealing with privacy concerns. We can see that the browser stores cookies for each application: To inspect a value from a cookie, let’s get into the Chrome DevTools window by clicking the F12 key and navigating to the Application tab. Now, where does the application store the cookies? It is stored in the user’s browser. Once we click “Forget Me”, the application removes the cookie and asks for the name again. Once we provide a name and click update, the application greets us:Įven if we close and reopen the application, we can see that the cookie value persists. NET/C# content and get paid? > JOIN US! <<
We use the Post version of the Index() method to get the value for userName from the form collection and assign it to the cookie.įor removing the cookie value, we use the RemoveCookie() endpoint. The Get version of the Index() method reads the UserName from the cookie and pass it to the view. String userName = form.ToString() ĬookieOptions option = new CookieOptions() Public IActionResult Index(IFormCollection form) Let’s create a new project and add a controller with endpoints to read and write values into cookies. Then we can use the cookie to access the user’s personalized settings, such as their preferred color theme. We can use the cookie to store some basic information like the user’s name. We often use cookies to personalize the content for a known user especially when we just identify a user without authentication.
Hence we should not use them to store sensitive information and their values should not be blindly trusted or used without proper validation. Users can easily tamper with or delete a cookie.
Most browsers restrict cookie size to 4096 bytes and only a limited number of cookies are available for each domain. Ideally, we should only store an identifier in the cookie and we should store the corresponding data using the application. Browsers send cookies with every request and hence their size should be kept to a minimum. CookiesĬookies store data in the user’s browser.

To download this article’s source code visit: State Management in ASP.NET Core Source Code. We strongly recommend visiting the complete navigation of this series: ASP.NET Core MVC Series. In this article, we are going to look at various approaches to HTTP state management that we can use in our application. We need to take additional steps to manage state between the requests. So HTTP requests are independent messages that don’t retain user values or app states.
