Andrei Zhemaituk created HTTPCLIENT-2255:
--------------------------------------------
Summary: NoHttpResponseException when using
BasicHttpClientConnectionManager
Key: HTTPCLIENT-2255
URL: https://issues.apache.org/jira/browse/HTTPCLIENT-2255
Project: HttpComponents HttpClient
Issue Type: Bug
Affects Versions: 4.5.14
Reporter: Andrei Zhemaituk
It seems BasicHttpClientConnectionManager does not validate connection before
leasing it (unlike PoolingHttpClientConnectionManager).
Sample code to reproduce:
{code:java}
@Test
void testDelayBetweenRequestsApacheHttpClient() throws Exception {
BasicHttpClientConnectionManager connectionManager = new
BasicHttpClientConnectionManager();
// PoolingHttpClientConnectionManager connectionManager = new
PoolingHttpClientConnectionManager();
// connectionManager.setDefaultMaxPerRoute(1);
try (CloseableHttpClient httpClient = HttpClients.custom()
.setConnectionManager(connectionManager)
.build()) {
HttpPost request = new
HttpPost("https://customsearch.googleapis.com/customsearch/v1";);
consume(httpClient.execute(request));
Thread.sleep(5 * 60 * 1000);
HttpPost request2 = new
HttpPost("https://customsearch.googleapis.com/customsearch/v1";);
consume(httpClient.execute(request2));
}
}
private static void consume(HttpResponse response) throws IOException {
InputStream content = response.getEntity().getContent();
while (content.read() != -1) {
}
content.close();
}
{code}
When using `BasicHttpClientConnectionManager` the above code fails to execute
second request:

On the other side when using `PoolingHttpClientConnectionManager`, connection
is successfully re-established and code executes successfully:
