How to clear a session on logout

I redirect the user to the login page when the user logs out, however I do not think that he clears any application or session, because all data is saved when the user logs in.

Currently, there is an input control on the login page, and the code on the page is only connected to the login authentication.

Can someone refer me to a good tutorial or article on handling login and logout from ASP.NET websites?

Session.Abandon()

I would prefer Session.Abandon()

Session.Clear() will not start End, and further requests from the client will not trigger a session start event.

I use the following to clear the session and clear the aspnet_sessionID :

 HttpContext.Current.Session.Clear(); HttpContext.Current.Session.Abandon(); HttpContext.Current.Response.Cookies.Add(new HttpCookie("ASP.NET_SessionId", ""));

Session.Abandon() destroys the session and the Session_OnEnd event Session_OnEnd .

Session.Clear() simply removes all values ​​(contents) from the object. session with the same key is still alive .

So, if you use Session.Abandon() , you will lose this particular session and the user will get a new session key . You can use it, for example, when the user logs out .

Use Session.Clear() if you want the user to remain in the same session (if you do not want him to translate the example) and reset all his data related to the session.

Go to the Global.asax.cs file in your project and add the following code.

  protected void Application_BeginRequest() { Response.Cache.SetCacheability(HttpCacheability.NoCache); Response.Cache.SetExpires(DateTime.Now.AddHours(-1)); Response.Cache.SetNoStore(); }
