ANNOUNCE: Pound - reverse proxy and load balancer - v0.2
by Robert Segall 03 Jun '02

03 Jun '02

This is to announce the release of Pound v0.2. Changes from previous version: - added HTTP/HTTPS request checking. Pound will only accept well-formed requests, thus protecting the back-end server(s) from malicious clients. I believe that this is now good enough to allow a ZServer to run without an Apache/Squid front-end (though you may still want Squid as a cache manager). - added request logging (can still be turned off with a flag). This means that now there is a central log with the correct client addresses. - fixed a few minor bugs. Many thanks to all the people who responded with suggestions and remarks. A few people asked why not simply use Squid rather than Pound. The answer is mostly a question of taste and philosophy: I believe a load-balancer should do no caching. The load-balancer, by its very nature, may become a bottle-neck for the whole system, and thus should be as light-weight as possible. If your application could really benefit from a front-end cache (which is not always the case) then put the caching proxy on the back-end server - e.g. between Pound and Zope - but allow Pound to run alone on a biggish machine. 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. For further information, download, etc. please see http://www.apsis.ch/pound The software is at version 0.2. Further testing (especially under heavy loads), improvements and bug (what bugs ?) fixes are welcome. Pound is distributed under the GPL. Enjoy and let me know how it works for you. -- Robert Segall Apsis GmbH Postfach, Uetikon am See, CH-8707 Tel: +41-1-920 4904

EuroPython2002: Extention of Early-Bird registration
by Tom Deprez 01 Jun '02

01 Jun '02

Hi, Due to the fact that at the end of the early-bird date, lot's of people waked up and registered for the congress (and because of the possible internet problems caused by the bancruptcy of KPNQwest), we've extended the early bird until 9th of June. We hope that the doubters among us, will find this interesting now that they are still able to profit from the early bird registration. But be warned, this is the final date! At the moment we've reached a total of more than 150 people at the EuroPython congress. That's already nice for a first congress, but it should be more.... Don't you think you could make great deals with people over there? There must be somebody to whom you can speak about a certain problem. With 150 people, it must be possible to make some friends or to see some old ones back... It can't be that Europe has only such a small group of Python and/or Zope developers/users. What about people outside of Europe? Have you seen the talks? It must be worthwhile to pay a visit to the conference.... and if not... well enjoy the Belgian beer, chocolates and food..... that's something I'm sure you will never forget! And now the early bird registration has been extended, .... so if you had doubts earlier, throw them away and just visit EuroPython2002! Don't forget to visit the http://europython.zope.nl/interviews page, which will be regulary updated with new interviews of people comming to EuroPython2002. Regards, EuroPython Team.
