Hello David, Warmup requests load your app's code into a new instance before any live requests reach that instance. You may find related detail on the "Configuring Warmup Requests to Improve Performance" documentation page <https://cloud.google.com/appengine/docs/standard/go/configuring-warmup-requests> .
Handler might be considered in a way optional, as you app would finally work as expected anyhow, even if request and response latency would likely prove higher without configured warmup requests. Expected response or functionality is related to the needed execution of per-instance one-time warmup and initialization actions. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
