Я использую общую библиотеку apache httpclient. Можно ли сделать HTTP-запрос через прокси? Более конкретно, мне нужно использовать список прокси для многопоточных запросов POST (сейчас я тестирую однопоточные запросы GET).
Я пытался использовать:
httpclient.getHostConfiguration().setProxy("67.177.104.230", 58720);
Я получаю ошибки с этим кодом:

Когда я удаляю эту строку, все работает нормально, как и ожидалось.
