Hi,
Since the purge keyword was removed in Varnish 4.1 I have been looking for a way
to purge an object transparently. The VCL I need to be able to replace is:
sub vcl_hit {
# purge cache when no-cache header present
if ( req.backend.healthy && !req.http.User-Agent ~ "(B|b)ot" &&
req.http.Cache-Control ~ "no-cache" ) {
purge;
}
}
return(purge) is useless as I don't want a page telling me my object has been
purged just the refreshed object. Obviously req.backend.healthy will be replaced
with std.healthy(req.backend_hint).
Any ideas?
Regards,
spaceman
