Hi Philip, I don't necessarily know the answer and it's possible that it is an error. I'll explain what it is doing and maybe that will help us move forward.
1) The request-bindings/raw is just an abstraction over request-post-data/raw (and the URI) 2) The request-post-data/raw is always #f for GETs, are you sure they are POSTs? 3) POSTs with multipart form data are converted into a request-bindings and the raw data is not made available, un-parsed. 4) If there's no Content-Length header, then even if there is data, then it is not exposed. I think that your problem may be (3). It sounds like you expect to see a copy of the raw data of the request all the time even if it has been parsed. (The logic of the current behavior is that at the "application" level there is no POST data, but there is only form data, but because of "transport" level constraints on the length of URIs it had to be sent in the data part of the transport layer.)
