I am trying to sort out how to post json and get a json reply.

i have a views endpoint here: /mobile

and at mydomain.com/mobile/views/mview?args=9288 i get an xml output as expected

also, from readme i used the HttpRequestor and send json to login using:
post to: mydomain.com/mobile/user/login
with this content: {"username":"blah","password":"blahblah"}

and this works.. :)

but if try posting to: mydomain.com/mobile/views/mview
with: {"args":"9288"}

i get 404
