The default inactivity timeout period is 600 seconds (10 minutes).
Session Inactivity Timeout describes how to change the default for all BIS sessions on this server.
The inactivity timeout can also be set in a
.srf file with the
SessionParms tag.
All calls to this function restart the timer. Specify
0 to restart the timer without changing the value currently in effect.
BIS/IIS defers processing this function until an
XMLExchange tag is processed. The main implication of this restriction is that if the client starts the program and then browses pages
that do not include an
XMLExchange tag while the program calls
B_SetInactivityTimeout() followed by
B_ReadRequest(), the updated inactivity timeout interval does not take effect until an
XMLExchange tag is processed. This is an unlikely scenario because there is no reason to start a service program if an
XMLExchange tag is not imminent.
