Create special $request_body variables with new nginx module

[smorin]

Basically there is the variable $request_body the is conditionally set.

I am looking to have our own module like

http://wiki.nginx.org/HttpEchoModule which has a directive echo_read_request_body which does this.

This will allow us to always have the data set in $request_body, but we are looking to have a new variable set. $raw_request_body, $decoded_request_body because usually $request_body when logged encodes from of the fields that are being submited so they are printable on a single log line. We want to have $raw_request_body represent the data send by the client with no encoding. We want to have $decoded_request_body represent the $raw_request but if submitted either with "application/x-www-form-urlencoded" or "multipart/form-data" be decoded to be the raw binary that was sent.
