Hi,
The scenario is as follows: I'm doing two consecutive requests to the
same host, using a multi-threaded (or thread safe) connection pool
manager. The first invocation has a timeout of 10s and the second has a
timeout of 30s.
In version 3.1 of HttpClient all works well, but in 4.0 I get a timeout
exception in the second request, after ~10 seconds, which means the
first timeout is used.
Looking at the code, I see that in version 3.1, the
HttpMethodDirector.executeWithRetry() method invokes a method named
applyConnectionParams() that took care of setting the timeout taken from
the request on the socket.
But in version 4.0, the only place I see the timeout is set on the
socket is when DefaultRequestDirector.execute(HttpHost, HttpRequest,
HttpContext) opens a connection using the managedConn.open() method.
Since the connection is reused between the requests, the second request
uses a socket with a timeout of the first request. As a (bad)
workaround, I put on the HttpClient instance a ConnectionReuseStrategy
that always says no to reusing the connection, so a new connection is
created for the second request, with the required timeout.
Am I missing something?
Thanks,
Moshe.
Hi Moshe
This is definitely a bug. Please raise a JIRA for this issue:
https://issues.apache.org/jira/browse/HTTPCLIENT
As a somewhat cleaner workaround you can obtain the actual connection
from the execution context and reset the timeout on that connection.
This at least will work for the response body.

DefaultHttpClient httpclient = new DefaultHttpClient();
HttpGet request = new HttpGet("http://www.google.com/";);
HttpContext context = new BasicHttpContext();
HttpResponse rsp = httpclient.execute(request, context);
HttpClientConnection conn = (HttpClientConnection) context.getAttribute(
ExecutionContext.HTTP_CONNECTION);
conn.setSocketTimeout(1000);
HttpEntity entity = rsp.getEntity();
System.out.println("----------------------------------------");
System.out.println(rsp.getStatusLine());
System.out.println("----------------------------------------");
if (entity != null) {
entity.consumeContent();
}
