I'm fine with a boolean to enable/disable compression, and it should be able to be done just like browsers, which can specify that they support compression so that the server knows whether it should use it, and even then it's optional. It'd certainly be nice if the HTTP libraries handled all of this for us, of course. -- Getting caught is the mother of invention. --Robert Byrne --------------------------------------------------------------------- Luke Kanies | http://reductivelabs.com | http://madstop.com --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Puppet Users" group.
