Betfair Streaming API

[rlebeau]

You see Betfair have two api's the HTTP Poling API which I have been using and to which you have already replied

That API uses HTTPS, which is HTTP over SSL/TLS. The SSLIOHandler.PassThrough controls the SSL/TLS handshake, and the TIdHTTP component sets the SSLIOHandler.PassThrough property for you on a per-connection basic as needed for each HTTP request.

there is also a TCP Streaming API which if I was looking to try and use

That API uses plain TCP over SSL/TLS. The TIdTCPClient component DOES NOT set the SSLIOHandler.PassThrough property for you, so you have to set it yourself when needed.
