HttpWebRequest^ myHttpWebRequest = (HttpWebRequest^)( WebRequest::Create( ourUri ) );
myHttpWebRequest->ProtocolVersion = HttpVersion::Version10;
// Sends the HttpWebRequest and waits for the response.
HttpWebResponse^ myHttpWebResponse = (HttpWebResponse^)( myHttpWebRequest->GetResponse() );
// Ensures that only Http/1.0 responses are accepted.
if ( myHttpWebResponse->ProtocolVersion != HttpVersion::Version10 )
{
   Console::WriteLine( "\nThe server responded with a version other than Http/1.0" );
}
else if ( myHttpWebResponse->StatusCode == HttpStatusCode::OK )
{
   Console::WriteLine( "\nRequest sent using version Http/1.0. Successfully received response with version HTTP/1.0 " );
}
// Releases the resources of the response.
myHttpWebResponse->Close();
