[DUG] Indy TidTCPServer question

[David Moorhouse (DUG)]

Hi Ross

It's up to you to implement a protocol (e.g. look at the http 
protocol).  Typically maintain some sort of header and payload.

The TCP layer will handle ensuring the messages are delivered, however 
you package the file up, unlike UDP.

Hope this helps
