Transferring Data Directly between 2 Connections in Indy (TIdContext)

ive a sever running TIdTCPServer, and Client Using Web Browser (or any other software) to Communicate, i dunno the protocol, but what im trying to do is to Send The Data between the client and another Connection (Both Connected to the same TIdTCPServer) for example the data sent by the first client is transmitted to the second client, and the data sent by the second client is transmitted to the first client, like a proxy (i cant really use a proxy server since its just this one condition) and the TIdTCPServer should still be receiving other clients and processing their data.

i stumbled upon the first line of code, since TIdContext.Connection.Socket.ReadLn requires a Delimiter, and the Client's Protocol is unknown to the server.

any ideas?

thanks.

You can look at the source code for TIdMappedPortTCP and TIdHTTPProxyServer to see how they pass arbitrary data between connections in both directions. Both components use TIdSocketList.SelectReadList() to detect when either connection has data to read. TIdMappedPortTCP then uses TIdBuffer.ExtractToBytes() and TIdIOHandler.Write(TIdBytes), whereas TIdHTTPProxyServer uses TIdTCPStream and TIdBuffer.ExtractToStream() instead.
