Im make post request using this method:
public String post(String url, String body) throws IOException {
HttpURLConnection connection = (HttpURLConnection) new URL(url).openConnection();
connection.setReadTimeout(SOCKET_TIMEOUT_MS);
connection.setDoOutput(true);
connection.setDefaultUseCaches(false);
connection.setConnectTimeout(SOCKET_TIMEOUT_MS);
connection.setRequestProperty(CONTENT_TYPE_HEADER, FORM_CONTENT_TYPE);
connection.setRequestProperty("User-Agent", USER_AGENT);
connection.setRequestProperty("Cookie", "");
HttpURLConnection connection = getConnection(url);
connection.setRequestMethod("POST");
connection.setDoOutput(true);
OutputStream stream = connection.getOutputStream();
stream.write(body.getBytes(StandardCharsets.UTF_8));
for (int i = 0; i < DEFAULT_RETRY_ATTEMPTS_NETWORK_ERROR_COUNT; i++) {
try {
connection.getResponseCode();
return;
} catch (IOException ex) {
getLogger().warning(ex.getLocalizedMessage());
}
}
return StringUtils.inputToString(connection.getInputStream());
}
But after a while, cookies begin to accumulate in it. Im write simple logger and get next result

After a while, the cookie becomes so large that the server does not accept the request. How can I turn this off, even if setRequestProperty("Cookie", "") doesn't help?
