Newcomer asks a question about FORMS verification!

jingling89

Excuse me, the initial development login verification system of my website background is verified by FORMS. I want to log in if I want to log out after logging in. How to write code? If it is session, it is better to write, but FORMS verification is written in cookies! Please help out! Thank you

What is the specific code, such as session.Abandon () if the session exits! Then Cookie.Remove ()
What? I want to completely delete the cookie generated from FORMS verification to the client!

FormsAuthentication.SignOut ()

If CookiesSupported is false, the SignOut method will remove the Forms authentication ticket information from the cookie or URL. You can use the SignOut method and the RedirectToLoginPage method in combination to log out a user and allow other users to log in
If running in cookieless mode exclusively, or if mixed mode is supported, the redirection to the login page should be explicitly controlled when special business logic is required after removing the anonymous identifier

I found using FormsAuthentication.SignOut ()
After exiting the system, you can also click the Back button to return to the previous page, but it will automatically jump to the landing page when refreshed again. Is there any way to make the page exiting to the landing page not back?

..... The pages you see back are just cached pages. Clear the cache after clearing cookies? Ha ha

There is an attribute of Page.Identity.Name, after you signout (), this attribute value is empty
You can try
Add to Page_Load ()

if (Page.Identity.Name == string.Empty)
{
.............................. Jumped.
}
Put it inside if (! Page.IsPostBack) or debug it by yourself
