HttpPost is being retried

Hello

We are using HttpPost method with DefaultHttpClient. The server processing
takes couple of minutes without any response during this time. I would
expect the HttpPost execution to timeout because POST method is not
repeatable. Instead it is repeated. Is this a bug?

9.3.2011 13:45:34 org.apache.http.impl.client.DefaultRequestDirector execute
INFO: I/O exception (org.apache.http.NoHttpResponseException) caught when
processing request: The target server failed to respond
9.3.2011 13:45:34 org.apache.http.impl.client.DefaultRequestDirector execute
INFO: Retrying request
9.3.2011 13:48:55 org.apache.http.impl.client.DefaultRequestDirector execute
INFO: I/O exception (org.apache.http.NoHttpResponseException) caught when
processing request: The target server failed to respond
9.3.2011 13:48:55 org.apache.http.impl.client.DefaultRequestDirector execute
INFO: Retrying request
... (loops forever)

Thanks in advnce
Best regards

Hi,

You may need to implement your own HttpRequestRetryHandler, as the one provided by default by http-client does a number of retries by default - DefaultHttpRequestRetryHandler.
You will need to set the new retry handler property on your HttpClient. See AbstractHttpClient setHttpRequestRetryHandler method.

Thanks for your answer. I am aware that I can somehow configure it (now I
know I have to implement my own HttpRequestRetryHandler) but I would expect
that DefaultHttpClient works like standards say: not to retry POST method.
This should be default behavior of the DefaultHttpClient without any extra
configuration. But I may be wrong. If so, please tell me why.

Thanks :-)
