+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions

+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+Each Contributor hereby grants You a world-wide, royalty-free,
+non-exclusive license:
+
+(a) under intellectual property rights (other than patent or trademark)
+    Licensable by such Contributor to use, reproduce, make available,
+    modify, display, perform, distribute, and otherwise exploit its
+    Contributions, either on an unmodified basis, with Modifications, or
+    as part of a Larger Work; and
+
+(b) under Patent Claims of such Contributor to make, use, sell, offer
+    for sale, have made, import, and otherwise transfer either its
+    Contributions or its Contributor Version.
+
+2.2. Effective Date
+
+The licenses granted in Section 2.1 with respect to any Contribution
+become effective for each Contribution on the date the Contributor first
+distributes such Contribution.
+
+2.3. Limitations on Grant Scope
+
+The licenses granted in this Section 2 are the only rights granted under
+this License. No additional rights or licenses will be implied from the
+distribution or licensing of Covered Software under this License.
+Notwithstanding Section 2.1(b) above, no patent license is granted by a
+Contributor:
+
+(a) for any code that a Contributor has removed from Covered Software;
+    or
+
+(b) for infringements caused by: (i) Your and any other third party's
+    modifications of Covered Software, or (ii) the combination of its
+    Contributions with other software (except as part of its Contributor
+    Version); or
+
+(c) under Patent Claims infringed by Covered Software in the absence of
+    its Contributions.
+
+This License does not grant any rights in the trademarks, service marks,
+or logos of any Contributor (except as may be necessary to comply with
+the notice requirements in Section 3.4).
+
+2.4. Subsequent Licenses
+
+No Contributor makes additional grants as a result of Your choice to
+distribute the Covered Software under a subsequent version of this
+License (see Section 10.2) or under the terms of a Secondary License (if
+permitted under the terms of Section 3.3).
+
+2.5. Representation
+
+Each Contributor represents that the Contributor believes its
+Contributions are its original creation(s) or it has sufficient rights
+to grant the rights to its Contributions conveyed by this License.
+
+2.6. Fair Use
+
+This License is not intended to limit any rights You have under
+applicable copyright doctrines of fair use, fair dealing, or other
+equivalents.
+
+2.7. Conditions
+
+Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
+in Section 2.1.
+
+3. Responsibilities
+-------------------
+
+3.1. Distribution of Source Form
+
+All distribution of Covered Software in Source Code Form, including any
+Modifications that You create or to which You contribute, must be under
+the terms of this License. You must inform recipients that the Source
+Code Form of the Covered Software is governed by the terms of this
+License, and how they can obtain a copy of this License. You may not
+attempt to alter or restrict the recipients' rights in the Source Code
+Form.
+
+3.2. Distribution of Executable Form
+
+If You distribute Covered Software in Executable Form then:
+
+(a) such Covered Software must also be made available in Source Code
+    Form, as described in Section 3.1, and You must inform recipients of
+    the Executable Form how they can obtain a copy of such Source Code
+    Form by reasonable means in a timely manner, at a charge no more
+    than the cost of distribution to the recipient; and
+
+(b) You may distribute such Executable Form under the terms of this
+    License, or sublicense it under different terms, provided that the
+    license for the Executable Form does not attempt to limit or alter
+    the recipients' rights in the Source Code Form under this License.
+
+3.3. Distribution of a Larger Work
+
+You may create and distribute a Larger Work under terms of Your choice,
+provided that You also comply with the requirements of this License for
+the Covered Software. If the Larger Work is a combination of Covered
+Software with a work governed by one or more Secondary Licenses, and the
+Covered Software is not Incompatible With Secondary Licenses, this
+License permits You to additionally distribute such Covered Software
+under the terms of such Secondary License(s), so that the recipient of
+the Larger Work may, at their option, further distribute the Covered
+Software under the terms of either this License or such Secondary
+License(s).
+
+3.4. Notices
+
+You may not remove or alter the substance of any license notices
+(including copyright notices, patent notices, disclaimers of warranty,
+or limitations of liability) contained within the Source Code Form of
+the Covered Software, except that You may alter any license notices to
+the extent required to remedy known factual inaccuracies.
+
+3.5. Application of Additional Terms
+
+You may choose to offer, and to charge a fee for, warranty, support,
+indemnity or liability obligations to one or more recipients of Covered
+Software. However, You may do so only on Your own behalf, and not on
+behalf of any Contributor. You must make it absolutely clear that any
+such warranty, support, indemnity, or liability obligation is offered by
+You alone, and You hereby agree to indemnify every Contributor for any
+liability incurred by such Contributor as a result of warranty, support,
+indemnity or liability terms You offer. You may include additional
+disclaimers of warranty and limitations of liability specific to any
+jurisdiction.
+
+4. Inability to Comply Due to Statute or Regulation
+---------------------------------------------------
+
+If it is impossible for You to comply with any of the terms of this
+License with respect to some or all of the Covered Software due to
+statute, judicial order, or regulation then You must: (a) comply with
+the terms of this License to the maximum extent possible; and (b)
+describe the limitations and the code they affect. Such description must
+be placed in a text file included with all distributions of the Covered
+Software under this License. Except to the extent prohibited by statute
+or regulation, such description must be sufficiently detailed for a
+recipient of ordinary skill to be able to understand it.
+
+5. Termination
+--------------
+
+5.1. The rights granted under this License will terminate automatically
+if You fail to comply with any of its terms. However, if You become
+compliant, then the rights granted under this License from a particular
+Contributor are reinstated (a) provisionally, unless and until such
+Contributor explicitly and finally terminates Your grants, and (b) on an
+ongoing basis, if such Contributor fails to notify You of the
+non-compliance by some reasonable means prior to 60 days after You have
+come back into compliance. Moreover, Your grants from a particular
+Contributor are reinstated on an ongoing basis if such Contributor
+notifies You of the non-compliance by some reasonable means, this is the
+first time You have received notice of non-compliance with this License
+from such Contributor, and You become compliant prior to 30 days after
+Your receipt of the notice.
+
+5.2. If You initiate litigation against any entity by asserting a patent
+infringement claim (excluding declaratory judgment actions,
+counter-claims, and cross-claims) alleging that a Contributor Version
+directly or indirectly infringes any patent, then the rights granted to
+You by any and all Contributors for the Covered Software under Section
+2.1 of this License shall terminate.
+
+5.3. In the event of termination under Sections 5.1 or 5.2 above, all
+end user license agreements (excluding distributors and resellers) which
+have been validly granted by You or Your distributors under this License
+prior to termination shall survive termination.

+*  statutory, including, without limitation, warranties that the       *
+*  Covered Software is free of defects, merchantable, fit for a        *
+*  particular purpose or non-infringing. The entire risk as to the     *
+*  quality and performance of the Covered Software is with You.        *
+*  Should any Covered Software prove defective in any respect, You     *
+*  (not any Contributor) assume the cost of any necessary servicing,   *
+*  repair, or correction. This disclaimer of warranty constitutes an   *
+*  essential part of this License. No use of any Covered Software is   *
+*  authorized under this License except under this disclaimer.         *
+*                                                                      *

+************************************************************************
+
+8. Litigation
+-------------
+
+Any litigation relating to this License may be brought only in the
+courts of a jurisdiction where the defendant maintains its principal
+place of business and such litigation shall be governed by laws of that
+jurisdiction, without reference to its conflict-of-law provisions.
+Nothing in this Section shall prevent a party's ability to bring
+cross-claims or counter-claims.
+
+9. Miscellaneous
+----------------
+
+This License represents the complete agreement concerning the subject
+matter hereof. If any provision of this License is held to be
+unenforceable, such provision shall be reformed only to the extent
+necessary to make it enforceable. Any law or regulation which provides
+that the language of a contract shall be construed against the drafter
+shall not be used to construe this License against a Contributor.
+
+10. Versions of the License
+---------------------------
+
+10.1. New Versions
+
+Mozilla Foundation is the license steward. Except as provided in Section

+
+Release 4.4 Final
+-------------------
+
+This is the first stable (GA) release of HttpClient 4.4. 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
+<https://publicsuffix.org/list>
+
+* 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.

+
+Release 4.3 Final
+-------------------
+
+This is the first stable (GA) release of HttpClient 4.3. The most notable enhancements included
+in this release are:
+
+* Support for Java 7 try-with-resources for resource management (connection release.)
+
+* Added fluent Builder classes for HttpEntity, HttpRequest, HttpClient and SSLContext instances.
+
+* Deprecation of preference and configuration API based on HttpParams interface in favor of
+constructor injection and plain configuration objects.
+
+* Reliance on object immutability instead of access synchronization for thread safety.
+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.

+
+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.
+  Contributed by Oleg Kalnichevski <olegk at apache.org>
+
+* [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 Poehlmann <rpn at methodpark.de>
+
+* [HTTPCLIENT-1179] Upgraded Commons Codec dependency to version 1.6

+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

+  self-signed certificates).
+
+* Simplified configuration for connection managers.
+
+* Transparent support for host multihoming.

+
+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.

+
+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:

+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.

+
+--------------------------------------
+
+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:

+  Bug ID: 4708535
+  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.
