We're back after a server migration that caused effbot.org to fall over a bit harder than expected. Expect some glitches.

An Asynchronous HTTP Client

The asyncore socket framework can be used to issue multiple HTTP requests at once, and handle incoming responses as they arrive.

For more information, and a sample implementation, see Building an RSS Newsreader, Part 1.

The effbot.org library contains an enhanced implementation, which includes support for HTTP 1.1 chunking and GZIP compression.
