Notable features and enhancements included in 4.4 series are: * Support for the latest HTTP state management specification (RFC 6265). Please note that the old cookie policy is still used by default for compatibility reasons. RFC 6265 compliant cookie policies need to be explicitly configured by the user. Please also note that as of next feature release support for Netscape draft, RFC 2109 and RFC 2965 cookie policies will be deprecated and disabled by default. 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.

Contributed by Oleg Kalnichevski Release 4.2.3 ------------------- HttpClient 4.2.3 (GA) is a bug fix release that addresses a number of issues reported since release 4.2.2. This release also includes a thoroughly reworked NTLM authentication engine which should result in a better compatibility with the newest Microsoft products. Users of HttpClient 4.x are advised to upgrade. Changelog ------------------- * [HTTPCLIENT-1296] NPE gets thrown if you combine a default host with a virtual host that has a -1 value for the port. Contributed by Karl Wright * [HTTPCLIENT-1290] 304 cached response never reused with If-modified-since conditional requests. Contributed by Francois-Xavier Bonnet * [HTTPCLIENT-1291] Absolute request URIs without an explicitly specified path are rewritten to have "/" path). Contributed by Oleg Kalnichevski * [HTTPCLIENT-1286] Request URI rewriting is inconsistent - URI fragments are not removed from absolute request URIs. Contributed by Oleg Kalnichevski * [HTTPCLIENT-1284] HttpClient incorrectly generates Host header when physical connection route differs from the host name specified in the request URI. Contributed by Oleg Kalnichevski * [HTTPCLIENT-1293] Kerberos and SPNego auth schemes use incorrect authorization header name when authenticating with a proxy. Contributed by Oleg Kalnichevski * [HTTPCLIENT-1283] NTLM needs to use Locale-independent form of toUpperCase(). Contributed by Karl Wright * [HTTPCLIENT-1279] Target host responding with status 407 (proxy authentication required) causes an NPE. Contributed by Oleg Kalnichevski * [HTTPCLIENT-1281] GzipDecompressingEntity does not release InputStream when an IOException occurs while reading the Gzip header Contributed by Francois-Xavier Bonnet * [HTTPCLIENT-1277] Caching client sends a 304 to an unconditional request. Contributed by Francois-Xavier Bonnet * [HTTPCLIENT-1278] Update NTLM documentation.

Contributed by Francois-Xavier Bonnet * [HTTPCLIENT-1273] DecompressingHttpClient does not automatically consume response content in case of an i/o, HTTP or runtime exception thrown by the decompressing protocol interceptor leading to a potential connection leak. Contributed by Oleg Kalnichevski * [HTTPCLIENT-1268] NTLM engine refactor fix, to correct a buffer overrun, and get NTLMv2 flags right.

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 * [HTTPCLIENT-1229] Fixed NPE in BasicClientConnectionManager that can be triggered by releasing connection after the connection manager has already been shut down. Contributed by Oleg Kalnichevski * [HTTPCLIENT-1227] Date parsing in DateUtils made more efficient. Contributed by Patrick Linskey * [HTTPCLIENT-1224] (regression) NTLM auth not retried after a redirect over a non-persistent connection.

Contributed by Oleg Kalnichevski * [HTTPCLIENT-1193] Fixed regression in the route tracking logic of the default connection manager causing cross-site redirect failures. 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. The fluent API exposes only the most fundamental functions of HttpClient and is intended for relatively simple use cases that do not require the full flexibility of HttpClient. However, the fluent API almost fully relieves the users from having to deal with connection management and resource deallocation. * Redesigned and rewritten connection management code. * Enhanced HTTP authentication API that enables HttpClient to handle more complex authentication scenarios. 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. Changelog ------------------- * [HTTPCLIENT-1187] If a revalidation response is deemed too old CachingHttpClient fails to consume its content resulting in a connection leak.
