POST content for form submission is defined in the forms section of
RFC1866 (HTML 2.0) and any later HTML RFCs. HTTP only specifies the
message format, not the format of payload data (and POST may be used for
other actions than HTML form submission)

Anyway, the format is very simple. It is a normal HTTP message with a
Content-Length and request body (much like a reply from a HTTP server).
Content-Type should be set to "application/x-www-form-urlencoded" and
the payload data is a URL encoded representation of the FORM contents
identical to how the query string is contstructed in a GET request.
