## Preface

HttpCore is a set of components implementing the most fundamental aspects of the HTTP protocol that are nonetheless sufficient to develop full-featured client-side and server-side HTTP services with a minimal footprint.

HttpCore has the following scope and goals:

## 1. HttpCore Scope

- A consistent API for building client / proxy / server side HTTP services

- A consistent API for building both synchronous and asynchronous HTTP services

- A set of low level components based on blocking (classic) and non-blocking (NIO) I/O models

## 2. HttpCore Goals

- Implementation of the most fundamental HTTP transport aspects

- Balance between good performance and the clarity & expressiveness of API

- Small (predictable) memory footprint

- Self-contained library (no external dependencies beyond JRE)

## 3. What HttpCore is NOT

- A replacement for HttpClient

- A replacement for Servlet APIs
