form身份验证通过后，只能用FormsAuthentication.RedirectFromLoginPage

复制代码 代码如下:

FormsAuthenticationTicket Ticket = new FormsAuthenticationTicket (1,"coffee",DateTime.Now, DateTime.Now.AddMinutes(20), false,UserRoles,"http://www.vevb.com/") ;

复制代码 代码如下:

string HashTicket = FormsAuthentication.Encrypt (Ticket) ;

复制代码 代码如下:

HttpCookie UserCookie = new HttpCookie(FormsAuthentication.FormsCookieName, HashTicket) ;
cookie.Domain = ".vevb.com";

复制代码 代码如下:

Response.Cookies.Add(UserCookie)

复制代码 代码如下:

Response.Redirect (Context.Request["ReturnUrl"]) ;
