HttpCore is a set of low level HTTP transport components that can be
used to build custom client and server side HTTP services with a
minimal footprint. HttpCore supports two I/O models: blocking I/O
model based on the classic Java I/O and non-blocking, event driven I/O
model based on Java NIO.

The blocking I/O model may be more appropriate for data intensive, low
latency scenarios, whereas the non-blocking model may be more
appropriate for high latency scenarios where raw data throughput is
less important than the ability to handle thousands of simultaneous
HTTP connections in a resource efficient manner.
