Puppet uses Net::HTTP on the client to connect to the puppetmaster. This is a part of the standard Ruby lib, and only in version 1.9 did they add content encoding Gzip support: http://redmine.ruby-lang.org/repositories/revision/ruby-19?rev=14187 So if you run your clients with ruby 1.9, then I think you can activate content-encoding compression in nginx. I doubt Luke would agree implementing the compression in the puppet layer of the protocol, because all the transfer use HTTP (especially when we'll move to a full REST system) and HTTP supports content-encoding since at least a decade. Now one solution to have compression in the client while running an older ruby interpreter version would be to dump Net::HTTP which is horribly slow and start using something "newer" (or simply better designed). -- Brice Figureau Days of Wonder http://www.daysofwonder.com --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Puppet Users" group.
