HTTP POST msg connection close problem

Problem:


when we are sending HTTP POST request (From C++ Program)- Connection got closed with "Connection reset by peer" mesaage after 5 transfers.

But , when we are doing a POST msg in the web browser, the same message getting accepted by apache. Not sure whether we are doing mistake in setting up the connection or some thing else.

Appriciate your time and advise on this.

Thanks

The c++ code snipet given below FYR...
