OnLoggedIn global event in ASP.net?

Is there a way to get notified when a user is registered with ASP.net?

Note . The user can log in without visiting the "login page". If the Remember Me cookie exists, it can go to an arbitrary page and log in.

When a user logs in, I want to get some information related to the session.

Note . There is an event Login.LoggedIn. The problem is that this control does not exist on every page; and one page on which it is present ( Login.aspx) does not raise an event OnLoggedIn.

Just like it Global.asaxhas a global session start notification in a session:

void Session_Start(object sender, EventArgs e) 
{
}

I assume somewhere there is an On User Logged In notification:

void LoggedIn(object sender, EventArgs e)
{
}

I think that you do not have a unique place for this. In my case (MVC + log4net) I use this:

  • In Global.asaxI check for authenticated users with an existing cookie.

    protected void Session_Start()
{
    string ip = HttpContext.Current.Request.UserHostAddress;

    log.InfoFormat("Starting session: {0} from {1}.",Session.SessionID, ip);

    if ((HttpContext.Current != null) &&
        (HttpContext.Current.User != null) &&
        (HttpContext.Current.User.Identity.IsAuthenticated) )
    {
        string user = HttpContext.Current.User.Identity.Name;
        string type = "Cookie";

        log.InfoFormat("User {0} logged in with {1}.", user, type);
    }

}

  • In my account controller, I check local logins (I use the Internet application template from MVC4, but you can do it in your own Login.OnLoggedInif you use web forms)

    [HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public ActionResult Login(LoginModel model, string returnUrl)
{
    if (ModelState.IsValid && WebSecurity.Login(model.EMail, model.Password, persistCookie: model.RememberMe))
    {
        string user = model.EMail;
        string type = "Forms";

        log.InfoFormat("User {0} logged in with {1}.", user, type);

        return RedirectToLocal(returnUrl);
    }

    // If we got this far, something failed, redisplay form
    ModelState.AddModelError("", "The user name or password provided is incorrect.");
    log.ErrorFormat("Bad password or user name. User={0}", model.EMail, model.Password);
    return View(model);
}

  • But I need to also check for OAuth logins, for example:

    [AllowAnonymous]
public ActionResult ExternalLoginCallback(string returnUrl)
{
    AuthenticationResult result = OAuthWebSecurity.VerifyAuthentication(Url.Action("ExternalLoginCallback", new { ReturnUrl = returnUrl }));
    if (!result.IsSuccessful)
    {
        log.Debug("External login failure.");

        return RedirectToAction("ExternalLoginFailure");
    }

    if (OAuthWebSecurity.Login(result.Provider, result.ProviderUserId, createPersistentCookie: false))
    {
        log.InfoFormat("User {0} logged in with External {1} login. External UserID = {2}",
            Membership.GetUser(OAuthWebSecurity.GetUserName(result.Provider, result.ProviderUserId)).UserName,
            result.Provider,
            result.ProviderUserId);

        return RedirectToLocal(returnUrl);
    }

    ...
}

    HttpCookie authCookie = Context.Request.Cookies[cookieName];

    if (null != authCookie)
    {
        // is logged in... check if the session needs init

    }   
}


protected void Application_AuthenticateRequest(Object sender, EventArgs e)
{
    //  check for logged in or not
    if(HttpContext.Current.User != null && 
        HttpContext.Current.User.Identity != null 
            && HttpContext.Current.User.Identity.IsAuthenticated)
    {
        // is logged in... check if the session needs init

    }
