Aidenk
+== 개요 ==
 특정 서버나 네트워크에 과도한 트래픽을 발생시켜 정상적인 서비스 제공을 방해하는 사이버 공격.
-r12
Aidenk
+원리는 requests로 서버에 과부화를 주는 것. --사실상 이코드로 DDos 공격은 불가능이다. 애초에 구글 도메인에 get을 해야하기에...--
-r1
Aidenk
-r8
Aidenk
+신기하게 깃허브에는 DDOS 코드가 존재한다...
-r16
Aidenk
+==# 예시 코드 #==
-r17
Aidenk
+이게 디도스가 맞나... 싶을 정도로 그냥 트래픽만 늘리는... post를 get으로 바꾸어야 정상적을 받을 수 있다.
-r21
Aidenk
+그냥 API 보내고 받을때 쓰는 아주 기초적인 코드다.
