About Apache HttpClient
Although the java.net package provides basic functionality for accessing
resources via HTTP, it doesn't provide the full flexibility or
functionality needed by many applications. HttpClient seeks to fill this
void by providing an efficient, up-to-date, and feature-rich package
implementing the client side of the most recent HTTP standards and
recommendations.
Designed for extension while providing robust support for the base HTTP
protocol, HttpClient may be of interest to anyone building HTTP-aware
client applications such as web browsers, web service clients, or
systems that leverage or extend the HTTP protocol for distributed
communication.
