The Apache HttpComponents project is pleased to announce 4.4 GA
release of HttpComponents HttpClient.

Notable features and enhancements included in 4.4 series are:

* Support for the latest HTTP state management specification (RFC 6265).
Please note that the old  cookie policy is still used by default for
compatibility reasons. RFC 6265 compliant cookie policies need to be
explicitly configured by the user. Please also note that as of next
feature release support for Netscape draft, RFC 2109 and RFC 2965 cookie
policies will be deprecated  and disabled by default. It is recommended
to use RFC 6265 compliant policies for new applications unless
compatibility with RFC 2109 and RFC 2965 is required and to migrate
existing applications to the default cookie policy.

* Enhanced, redesigned and rewritten default SSL hostname verifier with
improved RFC 2818 compliance

* Default SSL hostname verifier and default cookie policy now validate
certificate identity and cookie domain of origin against the public
suffix list maintained by <>

* More efficient stale connection checking: indiscriminate connection
checking which results in approximately 20 to 50 ms overhead per request
has been deprecated in favor of conditional connection state validation
(persistent connections are to be re-validated only if a specified
period inactivity has elapsed)

* Authentication cache thread-safety: authentication cache used by
HttpClient is now thread-safe and can be shared by multiple threads in
order to re-use authentication state for subsequent requests

* Native Windows Negotiate and NTLM via SSPI through JNA: when running
on Windows OS HttpClient configured to use native NTLM or SPNEGO
authentication schemes can make use of platform specific functionality
via JNA and current user credentials. This functionality is still
considered experimental, known to have compatibility issues and subject
to change without prior notice. Use at your discretion.

This release also includes all fixes from the stable 4.3.x release

Please note that as of 4.4 HttpClient requires Java 1.6 or newer.

About HttpComponents HttpClient

The Hyper-Text Transfer Protocol (HTTP) is perhaps the most significant
protocol used on the Internet today. Web services, network-enabled
appliances and the growth of network computing continue to expand the
role of the HTTP protocol beyond user-driven web browsers, while
increasing the number of applications that require HTTP support.

Although the 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

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
