Ah, I’m using Varnish 4.1, guess might have to look into >= 5.2. Thanks! :) Best Regards, Danila > On 12 Apr 2018, at 12:25, Guillaume Quintard > wrote: > > bereq.is_bgfetch? > > -- > Guillaume Quintard > > On Thu, Apr 12, 2018, 09:24 Danila Vershinin

Re: Softpurge and nearly immediate refresh?

Couldn’t really find anything useful besides obj.hits which indirectly tells us it’s a background fetch. So: sub vcl_deliver { if (req.http.grace == "normal(limited)" && obj.hits == 0 && req.http.Varied-Header = 'value1') { set req.http.Varied-Header = 'value2’; unset

Re: Softpurge and nearly immediate refresh?

So I guess I’m looking into having one background fetch trigger another background fetch (to sequentially refresh different object variants). In this fashion: 1. Client PURGE request will do softpurge.softpurge(); return(restart); with GET method, etc. which will all lead to "return deliver()"

Re: Softpurge and nearly immediate refresh?

Hi, That's indeed correct, a purge will kill all variations, and the restart only fetches one. The req.hash_always_miss trick however only kills/revalidate one variation. At this moment, we have no way to purge/revalidate all the object under one hash key. -- Guillaume Quintard On Wed, Apr

Re: Softpurge and nearly immediate refresh?

Hi Guillaume, A bit puzzled on something. If we use Vary: by some header.. am I correct that we need multiple restarts to refresh each object variation? Since the background fetch would only refresh the variation that matched initial purge request. Sent from my iPhone > On 9 Apr 2018, at

Hi Guillaume, This should absolutely work. Thank you :) Best Regards, Danila > On 9 Apr 2018, at 12:18, Guillaume Quintard > wrote: > > You can purge then set the method to GET then restart. Would that work for > you? signature.asc Description: Message

Re: Softpurge and nearly immediate refresh?

Hi, You can purge then set the method to GET then restart. Would that work for you? Other way is to use req.hash_always_miss that will only revalidate if we are able to fetch a new object. -- Guillaume Quintard On Sat, Apr 7, 2018 at 12:10 PM, Danila Vershinin wrote: > Hi,
