Is there a way to see what the current value and change it for the socket buffer size used by Apache Http Client?

Question

I'm using Apache HttpClient 4.3.x and was wondering if there's a way too see what is the current value for the socket buffer size used by it to send/receive data and if it's possible for me to change it?

Answer 1

I have not found a way to see the current value, but if you haven't provided a ConnectionConfig when building your HttpClient, it uses ConnectionConfig.DEFAULT which has a bufferSize of 8192.

You can specify a custom buffer size when building your HttpClient. For example,

int bufferSize = 42;
ConnectionConfig config = ConnectionConfig.custom().setBufferSize(bufferSize).build();

CloseableHttpClient httpClient = HttpClientBuilder.create()
                                    .setDefaultConnectionConfig(config)
                                    .build();
