Custom httpclient configuration

[Shih-liang, Chang]

Hi

I'm using the HttpClient 4.4. 
I am creating HttpClient instance using custom settings. Is the following 
configuration the same effect? or whats the different between them? I can’t 
find it in javadoc.
A.
SocketConfig socketConfig = SocketConfig.custom()
    .setSoTimeout(DEFAULT_SOCKET_TIMEOUT)
    .build();
CloseableHttpClient httpClient = HttpClients.custom()
     .setDefaultSocketConfig(socketConfig)
     .build();


B.


RequestConfig requestConfig = RequestConfig.custom()
    .setSocketTimeout(DEFAULT_SOCKET_TIMEOUT)
    .build();
CloseableHttpClient httpClient = HttpClients.custom()
     .setDefaultRequestConfig(requestConfig)
     .build();


Thanks in advance.
BR,
