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
|
|
|
|
-------------------
|
|
The following is a list of contributions tracked in JIRA.
|
|
Note that this is not a complete list of contributions or changes.
|
|
Since the API was redesigned completely, tracking everything outside
|
|
of the source code repository would have been too burdensome.
