Mesela buda adsense kodu; genel olarak mantık şu; veriler get ile forumxtr arkadaşın dediği gibi bir dosyaya çekilmiş burada adsense'i kodlayanlar açık vermemişler o konuda dosya adı belli değil muhtemelen bir python dosyası veriler yollandıktan sonra o dosyaya buradaki js kodlarının içinden direk "iframe" ile o dosyayı çağırmışlar dosya derlenmiş olarak iframe olarak ekrana yazdırılıncada malum reklamlar ekranda gözüküyor. kodların sonuna doğru bakarsanız iframe'li kısmı görürsünüz. Özellikle bu konuda bana epeyi fikir veren forumxtr arkadaşa çok teşekkür ediyorum.
