Altering the backend responseΒΆ
Here we override the TTL of a object coming from the backend if it matches certain criteria:
sub vcl_backend_response {
if (bereq.url ~ "\.(png|gif|jpg)$") {
unset beresp.http.set-cookie;
set beresp.ttl = 1h;
}
}
We also remove any Set-Cookie headers in order to avoid creation of a hit-for-miss object. See actions.
