A quick way to write an http endpoint to handle post body

[C K Kashyap]

Hi Alex et al,

I need a sample to handle HTTP post. All I need to do is listen for HTTP
post request, read the payload in the body and respond. Before you get
tempted to say a variation of RTFM - let me say that I promise to share an
interesting demo once I have that :)
