This release represents a complete, ground-up redesign and almost a complete rewrite of the old 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.

Notable changes and enhancements:

  • 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
