سلام
لطفا کمک کنید نیاز فوری دارم
من قطعه کدی به نام Ipn handler نوشته ام که در صورتی که فرد با سیستم paypal خرید کرد، paypal باید این کد را فراخوانی کند ، تا برنامه من چک کند که درست فراخوانی شده یا نه و در صورتی که درست یا نادرست باشد برای کاربر یک ایمیل می فرستد و وضعیت خرید را برای او ایمیل می کند ولی این کار صورت نمی گیرد. در واقع صفحه ipp.aspx من که توسط پارامتر "<input name=\"¬ify_url\" type=\"hidden\" value=\"http://www.test.ir/ipp.aspx\">"به paypal پاس داده می شود
