Pendrell: Twisted HTTP/1.1 User Agent for the Programmable Web

Pendrell augments the twisted.web framework with an HTTP 1client that has several advantages over prior art (or at least urllib2 and twisted.web.client):

• HTTP 1.1 support:

  • TE/transfer-encoding support for chunked, gzip, and deflate encodings

  • Ability to simultaneously maintain multiple persistent connections.

• Transparent gzip and deflate Content-encoding support.

• Ability to stream data, by performing call-backs with data chunks, alleviates the need to buffer large files.

  • Advanced gzip support accommodates incremental decoding of chunked streams.

• Asynchronous (twisted) API.

• Integration with cookielib, and compatibility with urllib2.Request API.

• Proxy Support.

Changelog

Version 0.3.3

• LRU requester cache cleanup.

Version 0.3.2

• Support servers that neither provide a content-length nor use chunked encoding.

Version 0.3.1

• Authorization caching eliminates unnecessary unauthorized responses.

Version 0.3.0

• Allow multiple Authenticators to be installed into Agent.authenticators.

• Modify errors.UnauthorizedResponse to handle multiple WWW-Authenticate header values.
