Answer 1

I finally solved my problem by adding Content-Length to the request.

When we do not add the Content-Length header to the request, NSURLConnection send it as a chunked request and it seems such problems is common with chunked requests.

Actually I do not found the root cause of the problem with this chunked request (I searched many subjects in web, reads many articles, talked with several other programmers but do not find any root cause, so I decide to use the other solution ) but I shared this solution for someone that can use non-chunked request in their business. As I know most usages of chunked requests are in real time streaming that we do not know the Content-Length so if you can add Content-Length, I suggest to use it for avoiding chunked problems like this.
