• "safe_mode" bakmaksızın FOLLOWLOCATION işlemini yerine getirebilir.
• Parametre alımını GET ve POST modüllerin array tipinde alabilir.
• cURL ile gelen header ile body değerlerini ayrıştırarak saklar.
• En çok kullanılan parametreleri hazır değişkenler ile ayarlayabilirsiniz.
• "curl_reset" fonksiyonuna bakmasızın bu işlemi gerçekleştirebilir.
