chas wrote I've often heard about the infinite-scalability that will be created by something like ZEO and I've always wondered about one thing : how is the load-balancing being done ?

There's a number of approaches you can take here: 1. Buy something - a cisco localdirector, an arrowpoint (also now owned by cisco), or similar. This is the approach we take - in a past life I've seen an LD get the absolute crap kicked out of it and it just kept working (it was in front of some _large_ proxy caches). www.cisco.com www.arrowpoint.com 2. Software - there's linux virtual server, there's eddieware, there's probably a bunch of commercial packages as well, although I don't know why you'd bother... www.linuxvirtualserver.org www.eddieware.org Which of these solutions you go for largely depends on your budget - the first set of options are probably more robust and flexible, but the latter is definately going to be cheaper :) Anthony -- Anthony Baxter <anthony@interlink.com.au> It's never too late to have a happy childhood.
