Unable to login through Varnish 4 cache

问题

I need some help. How can I do this in new version? since vcl_fetch is old and it is not accepeed now in Varnish 4.

sub vcl_fetch{
if (beresp.http.set-cookie ~ "sessionid" || beresp.http.set-cookie ~ "csrftoken") {
           return (pass);
         } else {
               return (deliver);
         }
}

回答1:

Vcl_fetch has been moved to vcl_backend_response.

That said it's not a good idea to return pass from vcl_backend_response. You should rewrite your return (pass) to

set beresp.uncacheable = true;
set beresp.ttl = 120s;
return (deliver);

Your whole vcl_backend_response should look like the following

sub vcl_fetch{
if (beresp.http.set-cookie ~ "sessionid" || beresp.http.set-cookie ~ "csrftoken") {
  set beresp.uncacheable = true;
  set beresp.ttl = 120s;
  return (deliver);
     } else {
           set beresp.ttl = 10s;
           set beresp.grace = 1h;
     }

}
