I'm getting Syntax errors on restart of varnish using the file above. As mentioned, I think there are some line-breaks throwing me off...

  • On line 25, their is line break after is_
  • On line 45, there is line break after "wordpress_test_cookie=[^;]+(;

Remove these two and works with Apache

How are POST requests handled with these settings?

shouldn't there exist something like


Do not cache example.com, the admin area,

logged-in users or POST requests

if (req.http.host ~ "example.com" ||
req.url ~ "^/admin" ||
req.http.Cookie ~ "logged_in" ||
req.request == "POST")
{
return (pass);

}


inside the vcl_recv block?
( I found this on https://www.linode.com/docs/websites/varnish/getting-started-with-varnish-cache)
