AFAIK, if you set content type to proper JSON content type, the browser
_will_ download the JSON response instead of dumping it into the window.
To make it dump into the window, I think it's best to first check the
_request_ header, and make sure it's not an XHR response, and then set
the response Content-Type header to 'text/plain'. In case of XHR, you
can leave it as 'application/json'.
The incoming header to check is 'HTTP_X_REQUESTED_WITH', which should be
set to 'XMLHttpRequest'. You set the response content-type to text/plain
if the header is either missing or set to something else than
'XMLHttpRequest'. I forgot the exact API for getting the headers, but
I'm sure you already know how to get them.
