Sure, you can override them:
set vcl_backend_response {
set beresp.ttl = 5m;
}

Dridi,
Supposedly, nginx has the ability to ignore the caching headers. Does Varnish
provide a similar mechanism?
Thanks,

The backend is telling Varnish, and ultimately the client, that the
response cannot be cached. Depending on your version of Varnish
it will indeed result in subsequent passed transaction.

Part 2 is written, but still an early draft so not published yet.
