Question

I try to upload an image to my webservice from my iphone application. The webservice is programmed in php. I have to send the image along with a device_id as multipart/form-data.

Something is wrong with my request because the server does not accept my device_id (invalid format). I am 100% positive that the device_id is correct because it works with my other requests.

I think there is something wrong with my request structure because Charles proxy cannot decode the multipart form-data.

Here is my request (sniffed with charles proxy):
