We revisit the same Form as the previous slide, except this time
the submission method is changed to POST.
In this case, we're going to try something different -- the CGI
program which is the target of this Form is going to show us the
actual HTTP request as it was received[2].
Again, try it.
[2] Actually, it's a
"reconstructed" version of the HTTP request: not all request
headers are necessarily shown. But it's close enough for our
purposes!
