How to Set Varnish Cache-Control Headers

Question

I am hoping someone can advise on the proper method for getting Varnish to send cache-control headers. Currently, my configuration is sending \"Cache-Control: no-cac

Answer 1

Varnish ignores Cache-Control: nocache as per the documentation. Here is evidence confirming that:

To get that result, you should detect the header Cache-Control .nocache. from your backend, and then invalidate the cache, set the backend response to not cacheable, or issue max-age: 0 in the other header (I forget the name right now).
