There is no need to upgrade Spring. You can upgrade HC dependency to something more recent without upgrading Spring itself. In this case however you should pass a custom instance of HttpClient to ClientHttpRequestFactory https://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/http/client/HttpComponentsClientHttpRequestFactory.html#HttpComponentsClientHttpRequestFactory-org.apache.http.client.HttpClient- > However, I don't see SO_KEEPALIVE parameter in the lastest Apache HC > javadocs in "The following parameters can be used to customize the behavior > of this class:" section: > https://hc.apache.org/httpcomponents-client-ga/httpclient/apidocs/org/apache/http/impl/client/DefaultHttpClient.html > > Could you please show me example how to set SO_KEEPALIVE parameter in new > versions of Apache HC? > --- SocketConfig socketConfig = SocketConfig.custom() .setSoKeepAlive(true) .build(); CloseableHttpClient client = HttpClientBuilder.create() .setDefaultSocketConfig(socketConfig) .build(); ClientHttpRequestFactory clientfactory = new HttpComponentsClientHttpRequestFactory(client); --- Hope this helps Oleg > Thanks, > Baratali Izmailov. > > On 12 May 2016 at 09:53, Oleg Kalnichevski <ol...@apache.org> wrote: > > > On Thu, 2016-05-12 at 09:23 +0100, Baratali Izmailov wrote: > > > Hello.
