hello Thao Thank you for trying but no, this does not help. If you want to build a single threaded scalable server using nonblocking i/o, you need to use exclusively nonblocking i/o. You can't conveniently block on one connection while it sorts itself out, as you put the other connections temporarily out of action. This is fine on a single connection server, but not if you want to support lots of connections.
Thanks anyway. Terry On Tue, 30 Jan 2007 14:11:42 -0600, "Dinh, Thao V CIV NSWCDD, K72" <[EMAIL PROTECTED]> said: > Terry > I ran into same problem a while ago.
