------------------------------------------
Summary: Improve extensibility of DefaultHttpRequestRetryHandler
Key: HTTPCLIENT-1207
URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1207
Project: HttpComponents HttpClient
Issue Type: Improvement
Components: HttpClient
Affects Versions: 4.2 Final
Reporter: Joshua Spiewak
Priority: Minor
Attachments:
Enable_sub-classes_to_modify_the_set_of_exceptions_that_are_rejected_for_retry.patch
Under certain circumstances, such as when a service is behind a load balancer,
it is desirable for a client to retry a request after timeout, rather than
simply extending the timeout. This would allow the client to connect to a
different service behind the load balancer.
Currently DefaultHttpRequestRetryHandler rejects four types of Exceptions for
retry, including InterruptedIOException, the parent class of
SocketTimeoutException. The attached patch collects the Exceptions into a Set,
and exposes the Set to sub-classes. This should allow sub-classes to remove
InterruptedIOException if they see fit, but still get the benefits of the other
logic in retryRequest, without copying the entire class.
