well, to the server end, i.e. I need to call "flush" on the client part.

Does it really matter on which end the flush can be done?

What I'm trying to do is something like this:

- server sends client a "get ready" packet, before starting to "bulk sending" data. Since this "get ready" may take some times/resources on the client side, it's better for the client to get prepare earlier before the "bulk transfer" begins.
- as soon as the "get ready" packet is flushed, the server starts immediatelly to bulk transfer data. It's up the the client if it wants to keep or drop the data, and the server doesn't care neither.

Since rx_FlushWrite closes the stream, the above scenario will not work.

Surelly there might be some other way to implement the above scenario, what I just have to implement it that way ;)

But any way, thanks for the reply.

best regards,
Soewono
