Question

I am trying to get some data from remote server. To achieve this I use HttpURLConnection. The problem is that sometimes the server after connection is established just hangs or what, doesn’t close connection, and I hang there. Also that hanged thread acquired the lock, so all all other threads are just sucking 😀
Code:

try {
        URL url = new URL(urlString);
        URLConnection urlConnection = url.openConnection();
        HttpURLConnection connection = (HttpURLConnection) urlConnection;

        BufferedReader br = new BufferedReader(new InputStreamReader(connection.getInputStream(), Charset.forName(CharEncoding.UTF_8)));
        StringBuilder sb = new StringBuilder();
        String line;
        while ((line = br.readLine()) != null) {

Last line is where we are hanging. I found method setConnectTimeout(timeout), but seems this is not the case because it is timeout before connection is established. What is common way to solve such situations?

Answer 1

assuming you meant timeout after the connection is established (likely during the read), how about something like this

URLConnection urlConnection = url.openConnection();
urlConnection.setConnectTimeout(c_timeout);
urlConnection.setReadTimeout(r_timeout);
stream = urlConnection.getInputStream();
