If you want to do it in code  use the System Web HttpCookie HttpOnly property   This is directly from the MSDN docs      Create a new HttpCookie  HttpCookie myHttpCookie   new HttpCookie  LastVisit   DateTime Now ToString        By default  the HttpOnly property is set to false     unless specified otherwise in configuration  myHttpCookie Name    MyHttpCookie   Response AppendCookie myHttpCookie      Show the name of the cookie  Response Write myHttpCookie Name      Create an HttpOnly cookie  HttpCookie myHttpOnlyCookie   new HttpCookie  LastVisit   DateTime Now ToString        Setting the HttpOnly value to true  makes    this cookie accessible only to ASP NET  myHttpOnlyCookie HttpOnly   true  myHttpOnlyCookie Name    MyHttpOnlyCookie   Response AppendCookie myHttpOnlyCookie      Show the name of the HttpOnly cookie  Response Write myHttpOnlyCookie Name     Doing it in code allows you to selectively choose which cookies are HttpOnly and which are not
