Raw Blame History

Changes since 4.2 BETA1
-------------------
* [HTTPCLIENT-1186] State of newly created connections in the connection pool is not always
correctly updated potentially allowing those connections to be leased to users with a different
security context.
Contributed by Ralf Pöhlmann <rpn at methodpark.de>
* [HTTPCLIENT-1179] Upgraded Commons Codec dependency to version 1.6
Contributed by Oleg Kalnichevski <olegk at apache.org>
* [HTTPCLIENT-1177] always remove fragments from request URIs
Contributed by Oleg Kalnichevski <olegk at apache.org>
Release 4.2 BETA1
-------------------
This is the first BETA release of HttpClient 4.2. This release completes development of several
notable enhancements in HttpClient:
* 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. As of release 4.2 HttpClient will be using
pooling connection manager per default.
* 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.

Release 4.2 ALPHA1
-------------------
This is the first ALPHA release of HttpClient 4.2. The 4.2 branch enhances HttpClient in several
key areas and includes several notable features and improvements:
* 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.

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.
Please note that new features included in this release are still considered experimental and
their API may change in the future ALPHA releases.

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<String> getVariantURIs() method and constructor
public HttpCacheEntry(Date requestDate, Date responseDate,
StatusLine statusLine, Header[] responseHeaders,
Resource resource, Set<String> 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 <olegk at apache.org>
* [HTTPCLIENT-1036] StringBody has incorrect default for characterset. (Default changed
to US-ASCII)
Contributed by Sebastian Bazley <sebb at apache.org>

Michajlo Matijkiw <michajlo_matijkiw at comcast.com>, and
Matthew Hawthorne <matthew_hawthorne at comcast.com>.
* [HTTPCLIENT-1033] HttpRoute.equals(Object o) is quite inefficient, as it does not take full
advantage of shortcut logic.
Contributed by Sebastian Bazley <sebb at apache.org>
* [HTTPCLIENT-1030] Implement "ignoreCookies" CookieSpec
Contributed by Sebastian Bazley <sebb at apache.org>

Release 4.1 ALPHA2
-------------------
HttpClient 4.1 ALPHA2 fixes a number of non-severe bugs discovered since
the last release and introduces support for two frequently requested features:
* HTTP/1.1 response caching
* transparent support for host multihoming

This is a bug fix release that addresses a number of issues discovered since
the previous stable release. None of the fixed bugs is considered critical.
Most notably this release eliminates eliminates dependency on JCIP annotations.
This release is also expected to improve performance by 5 to 10% due to
elimination of unnecessary Log object lookups by short-lived components.
Changelog
-------------------
* [HTTPCLIENT-895] Eliminated Log lookups in short lived objects impairing
performance.
Contributed by Oleg Kalnichevski <olegk at apache.org>

and Sebastian Bazley <sebb at apache.org>
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.

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.

-------------------
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:

Contributed by Johannes Koch <johannes.koch at fit.fraunhofer.de>
--------------------------------------
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.

--------------------------------------
Release 4.0 Alpha 1
-------------------
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.
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
-------------------
