What happens after that hasn't been configured and is starting to be way beyond the scope of what the Multimedia team should be involved with._______________________________________________On Wed, Mar 18, 2015 at 3:42 PM, Nuria Ruiz <nuria@wikimedia.org> wrote:Gilles:And we know this data is coming via varnishkafka into the cluster, right?

Note that there might be some loss of hits on browsers that don't support sendBeacon, since our fallback is a simple async AJAX request (we haven't tried to go beyond that with local storage and replaying the event, etc.) and this event might be fired in situations of tab/browser close as well as navigating away from the page. Thus keep in mind that a steady small increase of those hits over a long period of time might simply be the natural process of people upgrading their browsers to more modern ones.On Fri, Feb 6, 2015 at 4:46 PM, Nuria Ruiz <nuria@wikimedia.org> wrote:>A dummy image request seems rather reasonable. (I assume varnish can handle such load of "atypical" requests.)Right, the filtering for beacons is already in place in vcl and responses are sent right away so as far as I know there is no better place than varnish for this code.

Do you see any fundamental problem with this?
A dummy image request seems rather reasonable. (I assume varnish can handle such load of "atypical" requests.)
Making additional requests is ugly, but until we get SPDY our articles typically make dozens or hundreds requests, so the effect looks negligible.
