In this type of passthrough mode, Open Server does not recognize most types of events. Instead, Open Server invokes the full-passthrough event handler each time a network read for the connection completes.
Event handler passthrough mode is designed to enable client/server connections using per-packet security services (such as encryption) to use passthrough mode.
Regular passthrough mode requires that Open Server interpret packets to identify particular events. When packets are encrypted, this is not possible.
To use event handler passthrough mode for a thread:
Code a full-passthrough event handler and install it. For more information, see “Coding and installing a full passthrough event handler”.
Enable event handler passthrough mode for a thread by setting SRV_T_FULLPASSTHRU to CS_TRUE in the Open Server connection handler. For more information, see “Enabling event handler passthrough mode for a thread”.
Call routines to negotiate the TDS protocol level between the client and the target server. For more information, see “Negotiating the TDS protocol level”.
