http://support.microsoft.com/kb/977453 fixes a bug that causes IHttpConnection::IsConnected to return incorrect values. You should install it.
The error 0x800704CD corresponds to the message "An operation was attempted on a nonexistent network connection." I'm still fairly certain the client disconnected.
I also think you should follow my suggestion on how to use Redirect. If you continue to have problems, please use the "Contact Microsoft Support" link at
