This is to announce the release of Pound v0.4.

Changes from previous version:

- added code to disable a dead back-end server and to re-enable it once it 
comes back on-line.
- added HTTP/1.1 chunked transfer mode. This presumes a back-end HTTP/1.1 
server (which Zope is).
- added client time-outs to prevent blatant denial-of-service attacks.
- major code restructuring.

What is Pound (from the Web page)

- a reverse-proxy: it passes requests from client browsers to one or more 
back-end servers.
- a load balancer: it will distribute the requests from the client browsers 
among several back-end servers, while keeping session information.
- an SSL wrapper: Pound will decrypt HTTPS requests from client browsers and 
pass them as plain HTTP to the back-end browsers.
- an HTTP/HTTPS sanitizer: Pound will verify requests for correctness and 
accept only well-formed ones.
- an HTTP/1.1 to 1.0 proxy.
- a failover-server: should a back-end server fail, Pound will take note of 
the fact and stop passing requests to it until it recovers.

The software is at version 0.4 (beta quality). Further testing (especially 
under heavy loads), improvements and suggestions are welcome.

Pound is distributed under the GPL.

Enjoy and let me know how it works for you.
