Maybe this? https://tools.ietf.org/html/rfc3117 https://tools.ietf.org/html/rfc3117 There is a lot of "philosophy" about protocol design, which seems mostly sound. Although I wonder what happened to the protocol mentioned (BXXP or BEEP). I think HTTP was "good enough" as a universal application protocol? This one also talks about HTTP being wildly successful beyond its original design parameters: https://tools.ietf.org/html/rfc5218 https://tools.ietf.org/html/rfc5218
