The server committed a protocol violation. Section=ResponseStatusLine" For PHP webservice

I am calling a web service in my 开发者_如何学PythonC# Code. The webservice is bulit in PHP. I am calling its loadunload method. The webservice returns me the

"The server committed a protocol violation. Section=ResponseStatusLine"

error if I call the service with in 5 to 10 second delay. Here is the code I am using to call the service.

private MyServiceMachine client = new MyServiceMachine ();
client.loadunload();
Thanks in advance for help.

Here is the Excpetion I am getting Exception Details:

Another possibility: when doing a POST, the server responds with a 100 continue in an incorrect way.

This solved the problem for me:

request.ServicePoint.Expect100Continue = false;

Sounds like an error being returned by the C# HttpWebRequest class, rather than that by the endpoint server.

Turn on debugging is my reommendation.
