Subject [jira] [Updated] (HTTPCLIENT-1800) Why is Retry around Redirect and not the other way round
Date Thu, 05 Jan 2017 08:39:58 GMT

     [ https://issues.apache.org/jira/browse/HTTPCLIENT-1800?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Oleg Kalnichevski updated HTTPCLIENT-1800:
    Affects Version/s:     (was: 4.5.3)
        Fix Version/s: 5.0 Alpha2

This indeed looks like a bug.

> I am wondering, why the ServiceUnavailableRetryExec is before the RedirectExec in the
execChain of the the InternalHttpClient. I am referring to the HttpClientBuilder.build() method
where the execChain is put together something like this:
> Client -> ... -> ServiceUnavailableRetryExec -> RedirectExec -> ...
> We have the following scenario, where this causes an unexpected behavior and changing
the order would solve this:
> 1. We are sending a request to endpoint A which returns a 303 with the endpoint B in
the location-header
> 2. The RedirectExec redirects the request to B what returns a 503
> 3. Now the ServiceUnavailableRetryExec is doing its thing but retries to endpoint A
> I would expect the behavior of the client to retry to endpoint B instead of A. Is there
a reason why the chain is implemented this way around or is this a "bug".
> Any help very appreciated!
