HttpClient does not use a second connection to execute POST requests

The socket timeout defines the maximum period of inactivity between two
consecutive incoming IP packets, or in other words the maximum period of
time the socket can be blocked in a read operation

The connection timeout defines how long the socket can be blocked
waiting until the socket is ready to send and receive data. It has no
effect on read / write operations

See above

is made to the time I get a final response, what do I have to do?

It all depends what you mean by the connection timeout. The maximum time
until the response is received in its entirety?

Hope this helps
