안녕하세요.

카카오톡과 같은 채팅 앱을 만들고 있는데,

대화목록 등을 httpget으로 가져옵니다.

그런데, 이게 잘 가져오다가 가끔

이렇게 server connection이 refuse됩니다.
timeout될 때까지 접속이 안되다가, timeout지나고서는 또 바로 빠르게 접속이 됩니다.
그리고서 또 몇 번 서버랑 자료 주고 받다가 다시 갑자기 연결이 안되고 timeout이 나고요.
이유를 모르겠네요..

서버에 접속은 간단하게 아래와 같이 했습니다.

HttpPost request = new HttpPost($url);

ChatApplication.setHeader(request);

Vector<NameValuePair> nameValue = new Vector<NameValuePair>();

nameValue.add(new BasicNameValuePair("uid", $uid));

nameValue.add(new BasicNameValuePair("rid", $rid));

nameValue.add(new BasicNameValuePair("msg", $msg));

request.setEntity(makeEntity(nameValue));

HttpClient client = new DefaultHttpClient();

ResponseHandler<String> reshandler = new BasicResponseHandler();

res = client.execute(request, reshandler);


브라우저에서는 잘 작동하길래 혹시나해서 헤더에 각종 값들을 설정해줬습니다.(user-agent등)

그런데 그래도 이런 현상이 지속되네요.

log를 여기저기 찍어본 결과 client.execute부분에서 못 넘어가던데, 혹시 이유 아시는 분 계신가요?

서버는 cafe24쓰고, php로 만들었습니다.
