Question

Could someone explain me the difference between these two parameters?

1. org.apache.http.params.CoreConnectionPNames.CONNECTION_TIMEOUT;
2. org.apache.http.params.CoreConnectionPNames.SO_TIMEOUT.

According to the javadocs:

CoreConnectionPNames.CONNECTION_TIMEOUT:

Determines the timeout in milliseconds until a connection is
established. A timeout value of zero is interpreted as an infinite
timeout.

CoreConnectionPNames.SO_TIMEOUT:

Defines the socket timeout (SO_TIMEOUT) in milliseconds, which is the
timeout for waiting for data or, put differently, a maximum period
inactivity between two consecutive data packets).

So, for the first one, CoreConnectionPNames.CONNECTION_TIMEOUT, does it happen before any data is sent?
And for the second, CoreConnectionPNames.SO_TIMEOUT, does it mean that some data was already sent? Meaning that connection was successfully established.

Thanks.

Answer 1

does it happen before any data is sent?

Yes, it does.

does it mean that some data was already sent?

On HTTP level level, no, it does not. (TCP/IP or SSL may be a different story)

Meaning that connection was successfully established.

Yes, it does.
