When all objects in the cache at the time you issued the ban has either
been tested against it, or expired.
We have a "ban-lurker" thread which tries to speed this process up
by testing objects against the bans, but since there is no request
available, this thread can only test obj.* conditions, but not
req.* conditions.
One way to work around this limitation is to copy the fields you
want to test from req into obj:
sub vcl_fetch {
// copy url to object fo ban lurker
set beresp.http.XYZ-url = req.url;
}
sub vcl_deliver {
// don't deliver url to client
unset resp.http.XYZ-url;
}
ban obj.http.xyz-url ~ "*.jpg"
