[00:02:10] <milimetric>	 hm, yeah, I'd have to see how to identify requests with no responses from the varnish log.  But the bigger issue is that it would mean a bit of extra processing, and that it would run for all 150,000 requests/sec just to solve this one problem.  So I was trying to figure out if there was some way we could tag it so the standard process can just find it.
[00:30:27] <Krinkle>	 milimetric: it's not limited to 204, the same request can return non-empty as well (that's it's main purpose, the 204 is for when there were no changes since the last poll)
[00:30:40] <Krinkle>	 left a comment on-task with what I gathered
[00:31:46] <Krinkle>	 my suggestion, based on my limited knowledge of your needs, would be to discard anything that doesn't have a X-Analytics with one of page_id/special.
[00:32:12] <Krinkle>	 if anything without is is a valid pageview that you want to keep counting, we can tag that to be included.
[00:32:28] <Krinkle>	 I think trying to exclude would be a game of whack-a-mole
[00:33:12] <Krinkle>	 I listed three more cases unrelated to watchlist that are similarly in that blind spot and similarly not meant to be counted perhaps.
[11:08:01] <milimetric>	 That's an interesting approach, we've actually been trying to convince the WMF for a long time to let us do it.  Thanks for the additional examples, I'll think on it, this is great context either way.
