why `setConnectionRequestTimeout` doesn't stop my 1 min get request?
getConnectionRequestTimeout()
Returns the timeout in milliseconds used when requesting a connection from the connection manager.
getConnectTimeout()
Determines the timeout in milliseconds until a connection is established.
getSocketTimeout()
Defines the socket timeout (SO_TIMEOUT) in milliseconds, which is the timeout for waiting for data or, put differently, a maximum period inactivity between two consecutive data packets).
__
So, the first one, connectionRequestTimeout happens when you have a pool of connections and they are all busy, not allowing the connection manager to give you one connection to make the request.
connectTimeout happens when establishing the connection. For instance while doing the tcp handshake.
socketTimeout like the description says, is the timeout while waiting for data. Usually happens when your server is slow.

I have this code:
RequestConfig requestConfig = RequestConfig.custom() .setConnectTimeout(40 * 1000) .setConnectionRequestTimeout(40 * 1000) .setSocketTimeout(40 * 1000) .build(); client = HttpClientBuilder .create() .setDefaultRequestConfig(requestConfig) .build(); }
and
try { Stopwatch stopWatch = Stopwatch.createStarted(); response = client.execute(new HttpGet(routingRequestUrl)); stopWatch.stop(); } catch (Exception e) { answer.errorMsg = e.getMessage(); answer.latency = null; }
when my client configuration is as doesn't contain
.setSocketTimeout(40 * 1000)
- the stopWatch shows request can take more then 1 minute.It happens when I try
setConnectTimeout
andsetConnectionRequestTimeout
each alone or all together.Why is only
.setSocketTimeout(40 * 1000)
effectively checks timeout 40 seconds? and the other alone not?These are the prints:
Read timed out
Timeout waiting for connection from pool
Is the first triggered by
setConnectionRequestTimeout
and the second bysetSocketTimeout
? -
Elad Benda2 almost 9 yearsso if i want to terminate request that didn't return after 40 seconds I should use socketTimeout only ?

Welsh over 6 years@EladBenda2 unfortunately not, you will need create you're own wrapper that does an overall that could encompass the
connectionRequestTimeout
,connectTimeout
andsocketTimeout
. ThesocketTimeout
is the time in seconds between receiving bytes of data, so as long as you are receiving data it won't timeout.
