IE/NS have the same problem, but you don't see it because they simply try to connect again if the first connection attempt fails. You can do the same thing with REBOL. There is not much else you can do. Usually this is caused by incorrectly implemented workarounds for the SYN flood problem at the server, e.g. the SYN cookie scheme in some Linux versions. Under heavy load and in congested networks this can cause TCP protocol violations in the 3-way TCP handshake and can lead to timeouts at the client. -- Holger Kruse [holger--rebol--com]
