Users of HttpClient 4.2 are advised to upgrade. Changelog ------------------- * [HTTPCLIENT-1248] Default and lax redirect strategies should not convert requests redirected with 307 status to GET method. Contributed by Oleg Kalnichevski * [HTTPCLIENT-1215] BasicAuthCache does not take default ports into consideration when looking up cached authentication details by HttpHost key. Contributed by Oleg Kalnichevski * [HTTPCLIENT-1241] (regression) Preemptive BASIC authentication failure should be considered final and no further attempts to re-authenticate using the same credentials should be made.

Contributed by Oleg Kalnichevski Release 4.2 ------------------- This is the first stable (GA) release of HttpClient 4.2. The most notable enhancements included in this release are: * New facade API for HttpClient based on the concept of a fluent interface.

HttpClient 4.2 is now capable of making use of multiple authentication challenges and retry authentication with a fall-back scheme in case the primary one fails. This can be important for compatibility with Microsoft products that are often configured to use SPNEGO/Kerberos as the preferred authentication scheme.

IMPORTANT: please note that the HttpClient 3.x branch is now officially END OF LIFE and is no longer maintained and supported by the Apache HttpComponents project. Changelog ------------------- * The public API for the caching module had a minor change between 4.1-beta and 4.1-GA to the HttpCacheEntry class - the deprecated public Set getVariantURIs() method and constructor public HttpCacheEntry(Date requestDate, Date responseDate, StatusLine statusLine, Header[] responseHeaders, Resource resource, Set variants) were both removed. This will not affect you unless you are implementing new storage backends that use the deprecated code and/or are implementing custom serializers for cache entries. * Changed Browser-Compatibility and Best-Match cookie policies to emulate the behaviour of FireFox more closely when parsing Netscape style cookies. Comma will no longer be treated as a header element separator if Set-Cookie does not contain a Version attribute mandated by the RFC2109 / RFC 2965 cookie specifications.

Contributed by Oleg Kalnichevski and Sebastian Bazley Release 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 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. Some protected variables in connection management class have been made final in order to help ensure their thread safety: org.apache.http.conn.BasicEofSensorWatcher#attemptReuse org.apache.http.conn.BasicEofSensorWatcher#managedConn org.apache.http.impl.conn.DefaultClientConnectionOperator#schemeRegistry org.apache.http.impl.conn.DefaultHttpRoutePlanner#schemeRegistry org.apache.http.impl.conn.ProxySelectorRoutePlanner#schemeRegistry org.apache.http.impl.conn.SingleClientConnManager#alwaysShutDown org.apache.http.impl.conn.SingleClientConnManager#connOperator org.apache.http.impl.conn.SingleClientConnManager#schemeRegistry org.apache.http.impl.conn.tsccm.ThreadSafeClientConnManager#connOperator org.apache.http.impl.conn.tsccm.ThreadSafeClientConnManager#schemeRegistry Bug fixes since 4.0 BETA2 release ------------------- * [HTTPCLIENT-861] URIUtils#resolve is now compatible with all examples given in RFC 3986.

Contributed by Oleg Kalnichevski * DigestScheme can use an arbitrary digest algorithm requested by the target server (such as 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.

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. Contributed by Oleg Kalnichevski -------------------------------------- Release 4.0 Alpha 4 ------------------- ALPHA4 marks the completion of the overhaul of the connection management code in HttpClient. 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. Contributed by Oleg Kalnichevski * [HTTPCLIENT-763] Fixed problem with AbstractClientConnAdapter#abortConnection() not releasing the connection if called from the main execution thread while there is no blocking I/O operation. Contributed by Oleg Kalnichevski * [HTTPCLIENT-652] Added optional state attribute to managed client connections. This enables connection managers to correctly handle stateful connections. Contributed by Oleg Kalnichevski * [HTTPCLIENT-673] Revised max connections per route configuration Contributed by Oleg Kalnichevski * [HTTPCLIENT-753] Class Scheme and related classes moved to a separate package Contributed by Oleg Kalnichevski * [HTTPCLIENT-757] Improved request wrapping in the DefaultClientRequestDirector. This also fixed the problem with the default proxy set at the client level having no effect. Contributed by Oleg Kalnichevski * [HTTPCLIENT-734] Request abort will unblock the thread waiting for a connection Contributed by Sam Berlin * [HTTPCLIENT-759] Ensure release of connections back to the connection manager on exceptions. Contributed by Sam Berlin * [HTTPCLIENT-758] Fixed the use of generics in AbstractHttpClient #removeRequestInterceptorByClass and #removeResponseInterceptorByClass Contributed by Johannes Koch * [HTTPCLIENT-749] HttpParams beans Contributed by Stojce Dimski * [HTTPCLIENT-755] Workaround for known bugs in java.net.URI.resolve() Bug ID: 4708535 Contributed by Johannes Koch -------------------------------------- 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.
