| 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. |
