Well, by the time CFFILE runs, the file has already been uploaded to the
server. CFFILE just takes the uploaded file out of a temp directory and puts
it where you tell it to.

This basically works the same way, if I understand correctly. The file
itself is embedded in the HTTP POST response made by the browser. By the
time your server receives that response in its entirety, your server has the
file.
