HttpCore Overview

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.

Standards Compliance

HttpCore components strive to conform to the following specifications endorsed by the Internet Engineering Task Force (IETF) and the internet at large:

  • RFC 1945 - Hypertext Transfer Protocol -- HTTP/1.0
  • RFC 2616 - Hypertext Transfer Protocol -- HTTP/1.1
