I reread these sections as well as the examples and the read to me to be almost completely applicable/useful to both client and server - so am at a bit of a loss on how best to address this comment. Perhaps I'm just too close to the material. Can you provide a specific example of the type of improvement you'd like to see? Thank you for the comments!
