接收文件的服务器的响应是自动的还是必须手动编码？

Question

I am developing an iPhone application that sends through HTTP requests an XML file to my PHP server.
I have coded my server and got the XML file and stored it in database. Now I want to see from my iPhone if the server got my XML file.
This response of the server, I must code it or is it automatic?
If it is not automatic, how do I make it? I must make the server send back a simple XML to my iPhone stating that everything is "OK" and also program my iPhone application to get the XML?

Assuming you have set up some proper API for your App to query, just use HTTP Status Codes. If everything was ok and the data got successfully inserted, reply with a 200 response. If there was an error there are numerous other status codes to send, e.g. 500 internal server error. Your client App can then parse these responses and react appropietly.
