Content-switching is now fully implemented in haproxy 1.3.8. This one should be reasonably usable on non-critical productions by skilled adventurers. Many crash bugs were fixed, making it seem more robust than previous ones. Several speed improvements should noticeably reduce CPU usage on large sites.

I have finally published the article about Load Balancing. Take a look at it and give me some feedback.
> About me
My name is Willy Tarreau, I'm 32. I'm french, and I live in France at Chtillon. I'm a co-founder of EXOSEC which we started with Christophe Pouillet and Benoit Dolez in 2002 in order to provide managed security and high level auditing services to our customers. We have also created Exceliance whose goal is to design Linux-based specific appliances dedicated to security, performance and monitoring. Today, my work mostly consists in designing and auditing robust and scalable hosting infrastructures. This has led me to develop the HAProxy load balancer, which is used in several large infrastructures with high level of demand concerning availability, performance and security.
Since August 2006, I've become the new Linux Kernel 2.4 maintainer. I discovered Linux somewhat late, in 1994, when I was a student at the Magistre d'Informatique Applique de l'Ile de France (MIAIF). I started with SLS, a floppy-based distribution shipped with an unreliable kernel 1.0. I quickly understood that it would be much more fun to hack on this than it had been on DOS till then.
With a few buddies, we created the MIAIF web site of which I became the admin. I started hacking on the kernel to provide IDE hotplug to our poor server which had to reboot very often when we inserted our removable IDE racks (there was no USB at this time). I quickly liked hacking the kernel, in part because it was easy by then (only about 200k lines of code in 1.2.13). Since then, I got used to maintain my own tree with a lot of patches.
In 2001, with Benoit Dolez, we created our own distribution, Formilux, that we're still heavily relying on at Exosec. Its goal was to be very small, fast and robust. To achieve this, I merged even more patches in my kernels (2.2 then 2.4). I finally proposed Marcelo Tosatti to help him by maintaining a stable branch in parallel to his work (the hotfix tree). Late in 2005, he offered me to progressively take his place. We finally agreed that I would take over his task after 2.4.33 would be released.
