VLC code to enable purging

CODE:

acl purge {
        "localhost";
        "10.0.0.1";
}

sub vcl_recv {
        if (req.request == "PURGE") {
                if (!client.ip ~ purge) {
                        error 405 "Not allowed.";
                }
                lookup;
        }
}

sub vcl_hit {
        if (req.request == "PURGE") {
                set obj.ttl = 0s;
                error 200 "Purged.";
        }
}

sub vcl_miss {
        if (req.request == "PURGE") {
                error 404 "Not in cache.";
        }
}With this in your VCL file, we have implemented purging through HTTP. That means that if you now send a

CODE:

PURGE / HTTP/1.0to Varnish over port 80 (restricted to client with IP 10.0.0.1), your / document will be purged. However, this way of implementing purge does not support wildcard purge yet (because of restrictions in VCL).
