I was confused by the pass back of Request myself. I started using Cowboy
yesterday and wasn't sure if I needed to continue to pass the new Req
variable on down like:

{Q, R1} = cowboy_http_req:get_value(<<"**q">>, R),
{Id, R2} = cowboy_http_req:get_value(<<"id">>, R1)

And then return that R2 at the end of the function with the return tuple.

1) Do you?
2) "Again, the problem no longer exists!" -- What did that mean?
