I want to read the sessionid in cookie which is automatically generated by asp.net. such as ASP.NET_SessionId. but when i use javascript: document.cookie = "ASP.NET_SessionId=;" since i want to set the ASP.NET_SessionId to be empty.
but after the javascript executed, i found instead of change the ASP.NET_SessionId to empty, system generate a new cookie with ASP.NET_SessionId equal to empty.
why system not modify the cookie but generate a new one ?
Thanks!
