The HttpComponents project is pleased to announce the first stable (GA) release of Apache HttpClient 4.0
HttpClient 4.0 represents a complete, ground-up redesign and almost a complete rewrite of the HttpClient 3.x codeline. This release finally addresses several design flaws that existed since the 1.0 release and could not be fixed without a major code overhaul and breaking API compatibility. Architectural changes --------------------- * Redesign of the HttpClient internals addressing all known major architectural shortcomings of the 3.x codeline. * Cleaner, more flexible and expressive API. * More modular structure. * Better performance and smaller memory footprint due to a more efficient HTTP transport based on HttpCore. * Implementation of cross-cutting HTTP protocol aspects through protocol interceptors. * Improved connection management, better handling of persistent connections, support for stateful connections * Pluggable redirect and authentication handlers. * Improved support for sending requests via a proxy or a chain of proxies * More flexible SSL context customization * Reduced intermediate garbage in the process of generating HTTP requests and parsing HTTP responses All upstream projects are strongly encouraged to upgrade. Important notes ------------------- * Future releases of HttpMime module may be binary incompatible with this release due to possible API changes in Apache Mime4J. Apache Mime4J is still being actively developed and its API is considered unstable. * HttpClient 4.0 is not fully binary compatible with 4.0 BETA1 release.

For details please refer to <http://hc.apache.org/httpcomponents-client/ntlm.html> ------------------- 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. --------------------------------------------------------------------- To unsubscribe, e-mail: httpclient-users-unsubscr...@hc.apache.org For additional commands, e-mail: httpclient-users-h...@hc.apache.org
