It is recommended to use RFC 6265 compliant policies for new applications unless compatibility with RFC 2109 and RFC 2965 is required and to migrate existing applications to the default cookie policy. * Enhanced, redesigned and rewritten default SSL hostname verifier with improved RFC 2818 compliance. * Default SSL hostname verifier and default cookie policy now validate certificate identity and cookie domain of origin against the public suffix list maintained by Mozilla.org * More efficient stale connection checking: indiscriminate connection checking which results in approximately 20 to 50 ms overhead per request has been deprecated in favor of conditional connection state validation (persistent connections are to be re-validated only if a specified period inactivity has elapsed.) * Authentication cache thread-safety: authentication cache used by HttpClient is now thread-safe and can be shared by multiple threads in order to re-use authentication state for subsequent requests. * Native Windows Negotiate and NTLM via SSPI through JNA: when running on Windows OS HttpClient configured to use native NTLM or SPNEGO authentication schemes can make use of platform specific functionality via JNA and current user credentials. This functionality is still considered experimental, known to have compatibility issues and subject to change without prior notice. Use at your discretion. This release also includes all fixes from the stable 4.3.x release branch. Please note that as of 4.4 HttpClient requires Java 1.6 or newer.

Several old classes whose instances can be shared by multiple request exchanges have been replaced by immutable equivalents. * DefaultHttpClient, DecompressingHttpClient, CachingHttpClient and similar classes are deprecated in favor of builder classes that produce immutable HttpClient instances. * HttpClient builders now dynamically construct a request execution pipeline tailored specifically to the user configuration by physically excluding unnecessary protocol components. * There is now an option to construct a minimal HttpClient implementation that can only execute basic HTTP message exchanges without redirects, authentication, state management or proxy support. This feature might be of particular use in web crawler development. * There is now option to avoid strict URI syntax for request URIs by executing HTTP requests with an explicitly specified target host. HttpClient will no longer attempt to parse the request URI if it does not need to extract the target host from it. This release also includes all fixes from the stable 4.2.x release branch.

Contributed by Oleg Kalnichevski * [HTTPCLIENT-1053] Fixed the way DigestScheme generates nonce-count values. Contributed by Oleg Kalnichevski Release 4.1 ------------------- The HttpClient 4.1 release builds upon the stable foundation laid by HttpClient 4.0 and adds several functional improvements and popular features. * Response caching conditionally compliant with HTTP/1.1 specification (full compliance with MUST requirements, partial compliance with SHOULD requirements) * Full support for NTLMv1, NTLMv2, and NTLM2 Session authentication. The NTLM protocol code was kindly contributed by the Lucene Connector Framework project. * Support for SPNEGO/Kerberos authentication. * Persistence of authentication data between request executions within the same execution context. * Support for preemptive authentication for BASIC and DIGEST schemes. * Support for transparent content encoding. Please note transparent content encoding is not enabled per default in order to avoid conflicts with already existing custom content encoding solutions. * Mechanism to bypass the standard certificate trust verification (useful when dealing with self-signed certificates). * Simplified configuration for connection managers. * Transparent support for host multihoming. 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 * [HTTPCLIENT-1036] StringBody has incorrect default for characterset. (Default changed to US-ASCII) Contributed by Sebastian Bazley * [HTTPCLIENT-975] Support stale-if-error and stale-while-revalidate extension directive (RFC5861).

Contributed by Sebastian Bazley * [HTTPCLIENT-1030] Implement "ignoreCookies" CookieSpec Contributed by Sebastian Bazley Release 4.1 BETA1 ------------------- HttpClient 4.1 BETA1 finalizes the 4.1 API and brings a number of major improvements to the HTTP caching module. This release also adds full support for NTLMv1, NTLMv2, and NTLM2 Session authentication. The NTLM protocol code was kindly contributed by the Lucene Connector Framework project.
