I have a GCP App Engine running that serves a bunch of GET endpoints with a Cache-Control: public, max-age=86400 header. I notice that often, the responses are served from Google Edge Network and logged with a 204 code.

My question is, do these responses still count towards the Out Bandwith quota, or are they treated differently?

CodePudding user response：

The Google Frontend will cache content when Cache-Control is set to public.

Traffic delivered by Google services counts to your network egress quotas and costs. An HTTP 204 response is an egress network activity.
