Calling FormsAuthentication.SignOut() method using jquery

Question

I am using Asp.Net/C# in my project.I am using Forms Authentication.Currently I call FormsAuthentication.SignOut() on click of Asp.Net button.It works well , but my requirement is that I need to log out a user from horizontal menu option

Logout

That would be Html menu , so how do I call FormsAuthentication.SignOut() method when a user clicks Logout from the menu bar.Is there any solution possible or any other technique. Any suggestions are welcome. Thanks

FormsAuthentication.SignOut() is a server side code and you cannot directly invoke it from client side (i.e. browser) - instead, you need to create a URI that will do the same for you.

For example, you can have AJAX service that will call above code or simply speaking, you can have logout.aspx page that will call FormsAuthentication.SignOut() in say page_load. Such a URI can be invoked from jquery to get you what you want.

In your case, you should simply have a link to logout aspx page in your logout menu (or in menu click, write document.location = "/logout.aspx" which essentially means navigating to log-out page).

,thank you sir for making me understand it.What I would like to do is when the user clicks the logout link I need to redirect him to Login.aspx , my starting page.So on the page_load of Logout.aspx I must call the FormsAuth.Signout() method and then use Response.Redirect("Login.aspx"); , is it a proper approach.Thanks

@freebird, yes - that would do. Another approach is to pass some query parameter to login page (e.g. login.aspx?new_session) so that login page it self can call FormsAuth.Signout() - this will avoid one (unnecessary) server trip!

@VinayC Best idea so far. Clean with no extra load.

here you go:

    $('#logout').click(function () {
    $.ajax({
        url: '/logout',
        success: function () {
            document.location = '/logged_out';
        }, error: function () { 
            alert('Logout failed');
        }
    });
    return false;
  });
