During the review it was brought up that Beast could do a better job giving users control over the serialization and parsing of message payloads that have the chunked transfer coding applied. I collaborated with some helpful folks on the #boost slack channel and I have put together something solid for serializing chunks. I'm looking for feedback from anyone (especially Bjorn) before I merge this. The documentation is quite extensive and explains step by step how to achieve all of the goals stated in the review related to serialization of chunk encoded message payloads: <http://vinniefalco.github.io/stage/beast/bjorn/beast/using_http/chunked_encoding.html> I'm interested in hearing from anyone who cares to weigh in. Is the documentation sufficient? Are there any obvious defects? Do the interfaces meet the requirements for obtaining full control over the emitted chunked message payload? If anyone wants to play with or inspect the code, it is in the "bjorn" branch: <https://github.com/vinniefalco/Beast/commits/bjorn> In the meanwhile, I will start putting something together to provide better control during parsing of chunks. Thanks!
