Changes since 4.0 beta 1 ------------------- * DigestScheme can use an arbitrary digest algorithm requested by the target server (such SHA) as long as this algorithm is supported by the Java runtime. Contributed by Oleg Kalnichevski * Fixed parsing and validation of RFC2109 compliant Set-Cookie headers by the Best-Match cookie spec. Contributed by Oleg Kalnichevski * Fixed bug that can cause a managed connection to be returned from the pool in an inconsistent state. Contributed by Oleg Kalnichevski 4.0 Beta 1 ------------------- BETA1 release brings yet another round of API enhancements and improvements in the area of connection management. Among the most notable ones is the capability to handle stateful connections such as persistent NTLM connections and private key authenticated SSL connections. This is the first API stable release of HttpClient 4.0. All further releases in the 4.0 code line will maintain API compatibility with this release. There has been a number of important bug fixes since ALPHA4. All upstream projects are encouraged to upgrade to the latest release. Please note HttpClient currently provides only limited support for NTLM authentication. For details please see NTLM_SUPPORT.txt. ------------------- Changelog: ------------------- * [HTTPCLIENT-790] Protocol interceptors are now correctly invoked when executing CONNECT methods. Contributed by Oleg Kalnichevski * [HTTPCLIENT-668] Do not use static loggers. Contributed by Oleg Kalnichevski * [HTTPCLIENT-781] Respect Keep-Alive header's timeout value. Contributed by Sam Berlin * [HTTPCLIENT-779] Top-level classes (HttpClient, and HttpGet, HttpPut and similar HttpMethods) throw fewer checked exceptions. Contributed by Sam Berlin * HttpClient will throw an exception if an attempt is made to retry a request with a non-repeatable request entity. Contributed by Oleg Kalnichevski * Fixed request re-generation logic when retrying a failed request. Auto-generated headers will no accumulate. Contributed by Oleg Kalnichevski * [HTTPCLIENT-424] Preemptive authentication no longer limited to BASIC scheme only. HttpClient can be customized to authenticate preemptively with DIGEST scheme. Contributed by Oleg Kalnichevski * [HTTPCLIENT-670] Pluggable hostname resolver. Contributed by Oleg Kalnichevski * [HTTPCLIENT-719] Clone support for HTTP request and cookie objects. Contributed by Oleg Kalnichevski * [HTTPCLIENT-776] Fixed concurrency issues with AbstractPoolEntry. Contributed by Sam Berlin * Resolved a long standing problem with HttpClient not taking into account the user context when pooling / re-using connections. HttpClient now correctly handles stateful / user specific connections such as persistent NTLM connections and SSL connections with client side authentication. Contributed by Oleg Kalnichevski * [HTTPCLIENT-773] Improved handling of the 'expires' attribute by the 'Best Match' cookie spec. Contributed by Oleg Kalnichevski * Partial NTLM support (requires an external NTLM engine). For details see NTLM_SUPPORT.txt Contributed by Oleg Kalnichevski * Redesigned local execution context management.

All known shortcomings of the old HttpClient 3.x connection management API have been addressed. NTLM authentication remains the only missing major feature in the new codeline that prevents us from moving awards the API freeze. There has been a number of important bug fixes since ALPHA3. All upstream projects are encouraged to upgrade to the latest release. ------------------- HttpClient 3.x features that have NOT yet been ported: ------------------- * NTLM authentication scheme ------------------- Changelog: ------------------- * [HTTPCLIENT-765] String.toLowerCase() / toUpperCase() should specify Locale.ENGLISH Contributed by Sebastian Bazley * [HTTPCLIENT-769] Do not pool connection marked non-reusable.

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.
