I believe this pattern came about because browsers will resubmit POST
data if you don't issue a redirect after a POST request. If I submit a
form on your website and you render the response without redirecting,
then when I click "refresh" in the browser or advance one page and click
the browser's back button, the POST request gets submitted again.
It's also known as the PRG pattern:
