Zope 2.6 will include support for ICP. ICP allows Zope to exploit many of Squid's features, when using Squid as a front-end proxy. This includes load clustering, primitive load balancing, and automatic removal of dead Zope's. For the full story, see http://www.zope.org/Members/htrd/icp/intro I am currently thinking about updating that documentation before the 2.6 release, and I would appreciate any feedback from anyone who has been using ICP. thanks,
