Release 4.0 Alpha 3 ------------------- ALPHA3 release brings another round of API refinements and improvements in functionality. As of this release HttpClient requires Java 5 compatible runtime environment and takes full advantage of generics and new concurrency primitives. This release also introduces new default cookie policy that selects a cookie specification depending on the format of cookies sent by the target host. It is no longer necessary to know beforehand what kind of HTTP cookie support the target host provides. HttpClient is now able to pick up either a lenient or a strict cookie policy depending on the compliance level of the target host. Another notable improvement is a completely reworked support for multipart entities based on Apache mime4j library. ------------------- HttpClient 3.x features that have NOT yet been ported: ------------------- * NTLM authentication scheme ------------------- Changelog: ------------------- * [HTTPCLIENT-742] common interface for HttpRoute and RouteTracker Contributed by Roland Weber * [HTTPCLIENT-741] Fixed concurrency issues in AbstractClientConnAdapter.

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. The HttpClient 4.0 API is still very experimental and is bound to change during 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 major architectural shortcomings of the 3.x codeline * Cleaner, more flexible and expressive API * Better performance and smaller memory footprint due to a more efficient HTTP transport based on HttpCore. HttpClient 4.0 is expected to be 10% to 25% faster than HttpClient 3.x codeline * 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 ------------------- HttpClient 3.x features that have NOT yet been ported ------------------- * NTLM authentication scheme * RFC2965 cookie policy (Cookie2) * Support for multipart MIME coded entities ------------------- Changelog ------------------- The following is a list of contributions tracked in JIRA. Note that this is not a complete list of contributions or changes. Since the API was redesigned completely, tracking everything outside of the source code repository would have been too burdensome. * [HTTPCLIENT-655] User-Agent string no longer violates RFC Contributed by Oleg Kalnichevski * [HTTPCLIENT-541] Virtual host API redesign Contributed by Oleg Kalnichevski * [HTTPCLIENT-614] Allow for different strategies when checking CN of x509 certificates Contributed by Julius Davies * [HTTPCLIENT-136] Fixed inadequate proxy support Long standing architectural problem.
