Subject [jira] [Updated] (HTTPCLIENT-1456) ClientProtocolException occurs when retries after receiving 503
Date Thu, 06 Feb 2014 14:10:09 GMT

     [ https://issues.apache.org/jira/browse/HTTPCLIENT-1456?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Oleg Kalnichevski updated HTTPCLIENT-1456:
------------------------------------------

    Affects Version/s:     (was: 4.3.1)
        Fix Version/s: 4.3.3
           Issue Type: Bug  (was: Improvement)

The Content-Length header generated by the protocol pipeline should actually be removed prior
to re-trial of the request. This looks like a bug to me. I'll look into it.

> When HttpClient retries a POST request after receiving 503 (service temporary unavailable),
ClientProtocolException occurs. On second request, Content-Length header is already set and
the RequestContent created by HttpClientBuilder doesn't allow overriding it.
> There's a workaround:
> {code}
> HttpClientBuilder builder = HttpClientBuilder.create();
> builder.setServiceUnavailableRetryStrategy(new DefaultServiceUnavailableRetryStrategy(2,
100));
> builder.addInterceptorFirst(new HttpRequestInterceptor() {
>     @Override
>     public void process(HttpRequest request, HttpContext context) throws HttpException,
IOException {
>       if (request.containsHeader(HTTP.CONTENT_LEN)) {
>         request.removeHeaders(HTTP.CONTENT_LEN);
>       }
>     }
> });
> {code}
> I think HttpClientBuilder should provide an option like this:
> {code}
> HttpClientBuilder.create()
>   .setServiceUnavailableRetryStrategy(new DefaultServiceUnavailableRetryStrategy()
>   .enableOverrideContentLength()
>  ...
> {code}
