* Request the specified resource (sURL), and once the request is complete, notify done().

* Also, if dataPost is set to a string, that string can be used to control the response format;
* by default, the response format is plain text, but you can specify "bytes" to request arbitrary
* binary data, which should come back as a string of bytes.
*
* TODO: The "bytes" option works by calling overrideMimeType(), which was never a best practice.
* Instead, we should implement supported response types ("text" and "arraybuffer", at a minimum)
* by setting xmlHTTP.responseType to one of those values before calling xmlHTTP.send().

* @param {boolean} [fAsync] is true for an asynchronous request
* @param {function(string,string,number)} [done]
