using the max-age request header

Question

How do I configure my VLC to let Varnish respect the 'Cache-Control max-age' request header?

I noticed that by default varnish delivers cached content, even when I press F5 in my browser (Hence request a 'fresh' copy').

Answer 1

in vcl_hit you can do the following:

if (req.http.Cache-Control ~ '\no-cache\b`) {
    purge;
    return (restart);
}

make sure you have imported the std vmod

import std;
