登陆退出问题

dtcms安全退出：

Session[DTKeys.SESSION_ADMIN_INFO] = null;

Utils.WriteCookie("AdminName", "DTcms", -14400);

Utils.WriteCookie("AdminPwd", "DTcms", -14400);

Response.Redirect("login.aspx");

过程：清空session，设置cookie过期

public static void WriteCookie(string strName, string strValue, int expires)
{
HttpCookie cookie = HttpContext.Current.Request.Cookies[strName];
if (cookie == null)
{
cookie = new HttpCookie(strName);
}
cookie.Value = UrlEncode(strValue);
cookie.Expires = DateTime.Now.AddMinutes(expires);
HttpContext.Current.Response.AppendCookie(cookie);
}

而登陆时流程是：存session，写入日志，写入cookie
