Request.Post only deals with 'application/x-www-form-urlencoded' and 
'multipart/form-data" content type.

For other content type (like 'application/json'), you must read it 
manually from the standard input.

So you do something like that:

--8<----------------------------------------------------

if Request.Method = "POST" And If Request.ContentType = 
"application/json" Then

  sData = Read Request.ContentLength
  MyJsonData = JSON.FromString(sData)
  ...

Endif

--8<----------------------------------------------------
