Release 4.0 Alpha 1
-------------------
HttpClient represents a complete, ground-up redesign and almost a complete rewrite of the HttpClient
codeline. This release finally addresses several design flaws that existed since 1.0 release and
could not be fixed without a major code overhaul and breaking API compatibility.
HttpClient 4.0 API is still very experimental and is bound to change in the course of the ALPHA
development phase. Several important features have not yet been ported to the new API.
Architectural changes:
-------------------
* Redesign of the HttpClient internals addressing all known architectural shortcomings of
the 3.x codeline
* Cleaner, more flexible and expressive API
* More modular structure
* Pluggable redirect and authentication handlers
* Support for protocol incerceptors
* Improved connection management
* Improved support for sending requests via a proxy or a chain of proxies
* Improved handling redirects of entity enclosing requests
* More flexible SSL context customization
* Reduced intermediate garbage in the process of generating HTTP requests and parsing HTTP responses
-------------------
