Varnish 4

Good question! Don’t know, I’ve only tested it on 3!

Tested it now with Varnish 4.0.1 and got it working with this in the default.vcl:

acl invalidators {
        "127.0.0.1"
        "localhost";
        "<servers_hostname>";
        "<servers_ip>";
}
sub vcl_recv {
        if (req.method == "PURGE") {
               if (!client.ip ~ invalidators) {
                        return (synth(405, "Not allowed"));
               }
        return (purge);
        }
}

EDIT: I couldn’t get this to work before i added my servers public IP in the authorized client list. Edited the post to fit the results in case it might help someone else.

I know I’m superlate to this party but you got this plugin working with the above (the typical purge block) on v4 themystic? I only ask because I’m looking at the varnishlog and it LOOKS like the plugin is trying to use X-Purge-Method: regex, which according to the varnish guys that only ever worked with bans and the plugin is sending it as a purge request?

That’s how we get it to work right on DreamPress in order to flush the whole site.

Yea, I have that exact VCL setup and it is actually adding:

1424204803.726397 10 obj.http.X-Req-URL ~ /.* && obj.http.X-Req-Host == mydomain.com

to ban.list but it’s definitely not purging anything. curl -X PURGE https://domain.com DOES work fine and purges the homepage.

Does this work:

curl -X PURGE https://domain.com/.*

It appears that the dreamhost vcl file you linked to is for varnish 3.x, is that correct? I notice that adding in the appropriate pieces into varnish 4 config results in an error when restarting the varnish service.

The one I linked to? Yes. As I’ve repeatedly said, right now I don’t have a v4 VCL (we aren’t using it, and I’m not good enough at Varnish to build it out properly).
