Twisted Web2

Twisted.Web2 is the next generation web server built with Twisted. Web2 is under active development and its APIs should not be considered stable at this point. It is not a version of Twisted.Web and while the compatibility layer does support many, currently this is not the highest concern.

Improvements over Twisted.Web:

  • Streaming upload data
  • Support for multiple headers of the same name
  • Separation of low level HTTP and high level request handling which allows it to run under other transports such as SCGI and CGI
  • IResource API improvements from Nevow
  • More versatile outgoing data streaming API
  • Correct header parsing
  • Full HTTP/1.1 support
  • Output filters (HTTP range support in a generic fashion, and gzip support)
  • Significantly better URI Rewriting when used behind a proxy such as Apache's mod_proxy

Things to further improve

  • Speed, it's not very fast, depending on how the benchmarks are done it's either significantly faster than Twisted.Web or twice as slow.
  • Better twisted.web compatibility
  • More and better tests

Twisted Web2 is available under the MIT Free Software licence.



Documentation is available for Twisted Web2. An API reference of Twisted and all subprojects is also available.
