This variable applies only in a thin client environment. Using this configuration variable, you can direct the thin client to buffer some requests received from the server and process them later. When you set this variable to "1", the thin client buffers the requests received between the time that the client sends an event to the server and the time that the server informs the client that it has started the related event procedure. The events are processed only after the event procedure starts to prevent the thin client from processing requests that generate more events before the first event procedure has started. The default value of TC_DELAY_PRE_EVENT_OPS is "0".
