We are working in oracle ADF mobile application, in that we are facing one issue on deploying the application in the iOS device.
We are able to download data through simulator on local machine. But when the same build is deployed on device and tested with public server, we are not able to download data and it says "Server returned HTTP response code: 411".
this error indicates a missing content length information, which however is not relevant for get requests (data queries). I am not sure that what you see is related to iOS as a platform but most likely to the public site you deployed the service to (not sure whether you own it or not). IS the service SOAP or REST and does the public site support POST requests being sent to the server ?
