I get the following response on purging using x-key
image

I have used the file storage backend using this :
varnishd -F -s disk=file,/var/lib/varnish/varnish_storage.bin,1G -f /etc/varnish/default.vcl -a:6085
and my purging logs are :

Don't know why my storage is malloc Transient in this case when I am using file type storage backend could be the source of the issue

my VCL file is

`
sub vcl_recv {
if (req.method == "PURGE") {

    if (req.http.x-key) {
    set req.http.n-gone = xkey.purge(req.http.x-key);
    # or: set req.http.n-gone = xkey.softpurge(req.http.xkey)
    return (synth(200, "Invalidated "+req.http.n-gone+" objects"));
    } else {
    return (purge);
    }
 }

}

sub vcl_backend_response {
// set beresp.storage = disk;
set beresp.ttl = 0s;
if(bereq.url ~ "date"){
unset beresp.http.Cache-Control;
set beresp.http.Cache-Control = "public";
set beresp.ttl = 10m;
set beresp.http.x-key = "date";
std.log("setting cache-control");
}
}

hi @Aadarsh-Verma ,

this doesn't look like a bug so I'll close this.
