// noheaders.c: build a complete HTTP reply -without any response header
//              (this useful to send a raw JSON reply for example)
//
//              Returning an INVALID HTTP status code in the 1-99 range 
//              (inclusive) will prevent G-WAN from injecting the missing
//              response HTTP Headers.
// Notes:
//
// This reply is supposed to be fetched by Javascript code running in the 
// browser, see the comet.c example for an illustration.
//
// When the "Content-Length" HTTP header is present, browsers don't have to 
// wait more than the time needed to load the specified amount of data.
//
// The lack of a "Content-Length" HTTP header is forcing Internet Browsers 
// to guess when to stop waiting for more data (they wait for a while, 
// without displaying anything, and then, after a timeout, they display 
// everything they have received).
