I'm developing a Windows 8 app that communicates with a node.js server using node.js/socket.io, and have ran into a pile of issues with connecting. I decided to run a tcp sniffer application (microsoft network monitor 3.4), and noticed that before sending the http request, there is a bunch of garbage in my string:

(the dots are \r\n in most cases)
Although I am using port 443, this is not a secured websocket - I am forced to use 443 because some smart phones only allow websockets to create socket connections on that port.
In C++, I am creating the websocket like so:
void Websocket::Connect(Platform::String ^host)
{
if ( this->socket != nullptr ) return;
try
{
Uri^ address = ref new Uri(host);
readBuffer = ref new Buffer(1000);
this->socket = ref new MessageWebSocket();
this->socket->Control->MessageType = SocketMessageType::Utf8;
this->socket->Control->MaxMessageSize = 512;
this->socket->Closed += ref new TypedEventHandler<IWebSocket^, WebSocketClosedEventArgs^>( this, &Websocket::ServerClosed );
this->socket->MessageReceived += ref new TypedEventHandler<MessageWebSocket^, MessageWebSocketMessageReceivedEventArgs^>( this, &Websocket::MessageRecv );
create_task(this->socket->ConnectAsync(address)).then([this](task<void> previousTask)
{
try
{
concurrency::task_status status = previousTask.wait();
switch( status ) {
case concurrency::task_status::completed:
this->connected = true;
break;
default:
socketErrorString = ref new Platform::String( L"Connection was cancelled" );
}
}
catch(Exception^ exception)
{
this->connected = false;
socketErrorString = ref new Platform::String( exception->Message->Data() );
this->socket = nullptr;
} catch( ... ) {
this->connected = false;
socketErrorString = ref new Platform::String( L"Unknown exception caught (inside connect)" );
this->socket = nullptr;
}
});
} catch( Exception ^exc ) {
this->connected = false;
socketErrorString = exc->Message; //ref new Platform::String( L"Unknown exception caught (outside connect)" );
this->socket = nullptr;
}
}
I can't see any sort of issue in the code, so I was hoping a few other sets of eyes may be able to. Thanks.
