You can also use gcloud beta compute backend-service update $NAME --cache-mode=FORCE_CACHE_ALL to forcibly cache the responses (as of gcloud SDK 309.0.x).

Is that going to force the browser to cache the response and result in vacuously fast response times after the first one?

Only our side - it is effectively s-maxage. You can use --client-ttl=0 to force revalidation on the client or --custom-response-header=‘Cache-Control: no-cache’ to prevent browser caching entirely. https://developer.mozilla.org/en-US/docs/Web/HTTP/Caching#Controlling_caching The new gcloud should roll out tomorrow/this week.
