Quick fix to removal of Cookie..

 

If you are new to using cookies then probably you must have wrote similar to the below code to Add & Remove cookies.

 

 

 Adding Cookie:

 

 HttpCookie test = new HttpCookie("Test");
            test.Value = "Testing Data";
            Response.Cookies.Add(test);

 

Removing Cookie: Either of one.

 

        Response.Cookies.Remove("Test");
        Response.Cookies.Clear();

 

But removal of cookie does not work this way.

 

Reason:

 

Remove() and Clear() remove a cookie instance or all cookies from the Response respectively.

They do not do anything on the client, it is a disconnected architecture. Therefore, in order to invalidate (remove) the cookie from the Request as sent by the client - for the next request and subsequent requests you need a quick fix.

Quick Fix:

Set the cookie expirey to be less than the next request time

 

Response.Cookies["Test"].Expires = DateTime.Now.AddDays(-1);

 

 

Hope it it useful.
