I have php api call which return some response headers. When i try to hit the api call with http i get the response header as it is but when i try to do the same thing with https in the url all the response headers get converted to lower case on the ios side.
header('X-Session-Id: '.$x_session_id);
Resonse Header:
x-session-id : "ABCD"
What am I missing here?
