What type of sessions in asp.net

The Session object stores information about, or change settings for a user session. You can store in the Session object any number of key-value pairs. So you can store a value in the Session object on any page through the code line given below.

It makes it possible to obtain the value at a later point in time. You may issue the statement below to retrieve a value. Then we will retrieve the value and display it accordingly on the page.

In ASP. NET There are 2 types of events available. We can handle both sessions in a global. InProc:- In the same process as a calling application, an inproc client runs. It is similar to a normal call on a dll function.

The ASP. NET worker thread handles the location of the memory. To manage these, it only involves a significant overhead for the worker thread. If your custom class supports cookieless session identifiers, you must implement a solution for sending and retrieving session identifiers in the URL. NET session state supports several storage options for session variables. Each option is identified as a session-state Mode type.

The default behavior is to store session variables in the memory space of the ASP. NET worker process. However, you can also specify that session state should be stored in a separate process, in a SQL Server database, or in a custom data source.

If you do not want session state enabled for your application, you can set the session mode to Off. NET provides two events that help you manage user sessions. Session events are specified in the Global.

If the Global. NET application is modified, the application will be restarted and any values stored in application state or session state will be lost.

Be aware that some anti-virus software can update the last-modified date and time of the Global. For more information, see Session-State Events. Session state is configured by using the sessionState element of the system. You can also configure session state by using the EnableSessionState value in the Page directive. The session Timeout value. Supporting values that are based on the session Mode setting. The following example shows a sessionState element that configures an application for SQLServer session mode.

It sets the Timeout value to 30 minutes, and specifies that session identifiers are stored in the URL. You can disable session state for an application by setting the session-state mode to Off. If you want to disable session state for only a particular page of an application, you can set the EnableSessionState value in the Page directive to false.

The EnableSessionState value can also be set to ReadOnly to provide read-only access to session variables. Access to ASP. NET session state is exclusive per session, which means that if two different users make concurrent requests, access to each separate session is granted concurrently. However, if two concurrent requests are made for the same session by using the same SessionID value , the first request gets exclusive access to the session information.

The second request executes only after the first request is finished. The second session can also get access if the exclusive lock on the information is freed because the first request exceeds the lock time-out.

If the EnableSessionState value in the Page directive is set to ReadOnly, a request for the read-only session information does not result in an exclusive lock on the session data. However, read-only requests for session data might still have to wait for a lock set by a read-write request for session data to clear. How to: Save Values in Session State.

Custom: this enables you to store session data using a custom storage provider. Application Object. An application on the Web may consists of several ASP files that work together to perform some purpose. The Application object is used to tie these files together. The Application object is used to store and access variables from any page, just like the Session object. PostBack is the name given to the process of submitting an ASP. NET page to the server for processing. PostBack is done if certain credentials of the page are to be checked against some sources such as verification of username and password using database.

PHP Session. PHP session is used to store and pass information from one page to another temporarily until user close the website. PHP session creates unique user id for each browser to recognize the user and avoid conflict between multiple browsers. Session simply means a particular interval of time.

Session Tracking is a way to maintain state data of an user. It is also known as session management in servlet. Each time user requests to the server, server treats the request as the new request. 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. Sessions are slightly different.

Each user gets a session ID, which is sent back to the server for validation either by cookie or by GET variable. Sessions are usually short-lived, which makes them ideal in saving temporary state between applications. Sessions also expire once the user closes the browser.
