How session is maintained in Web application?
Sessions are maintained automatically by a session cookie that is sent to the client when the session is first created. The session cookie contains the session ID, which identifies the client to the browser on each successive interaction. You can also edit the session-properties element in the server.
How do web applications use sessions to maintain state?
Client-side sessions use cookies and cryptographic techniques to maintain state without storing as much data on the server. When presenting a dynamic web page, the server sends the current state data to the client (web browser) in the form of a cookie. The client saves the cookie in memory or on disk.
How do you manage session state?
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.
Why state is a problem in web application?
In general application design, there are other concerns around client-side state as the state could get quite large so the constraints on the client storage could be onerous, it may be difficult to serialize and so serialization to the client could be difficult, or the network performance could be significant.
What is a session state?
Session state, in the context of . NET, is a method keep track of the a user session during a series of HTTP requests. Session state allows a developer to store data about a user as he/she navigates through ASP.NET web pages in a . The concept of a session is generic and applies to most web servers.
What are the alternatives to session state in ASP.NET?
Alternatives to session state include the following: Application state, which stores variables that can be accessed by all users of an ASP.NET application. Profile properties, which persists user values in a data store without expiring them. ASP.NET caching, which stores values in memory that is available to all ASP.NET applications.
How does a web application maintain session state?
There are multiple mechanisms available in HTTP to maintain session state within web applications, such as cookies (standard HTTP header), URL parameters (URL rewriting – RFC2396 ), URL arguments on GET requests, body arguments on POST requests, such as hidden form fields (HTML forms), or proprietary HTTP headers.
Why is session _ onEnd event not supported in ASP.NET?
The Session_OnEnd event is not supported if the session Mode property is set to a value other than InProc, which is the default mode. If the Global.asax file or Web.config file for an ASP.NET application is modified, the application will be restarted and any values stored in application state or session state will be lost.
How to implement a custom session state provider?
You can implement a custom session-state store provider by creating a class that inherits the SessionStateStoreProviderBase class. For more information, see the “Required Classes” section later in this topic.
