trunk sends the deprecation INFO message when setting Cache-control via the addAdditionalHeaders hack.
The Cache-control header setting is important for trying to interoperate with certain browsers. I searched but did not find any traffic on the planned means for supporting it. I'd love to try to contribute bits to land this one item in 1.1 if somebody can point me to the right guidance on how Restlet should support it. I have always treated this as an explicit setting made by code, never intuited by other behavior, so a simple setCacheControl(Message.CACHE_CONTROL_NO_CACHE) or something like that would do for my purposes ... but happy to run down the road of something more elegant if someone's already thunk it up. - Rob
