Have decorated an Action method with ContentOutputCache attribute, and have set the Duration to 900 sec.
1) First load it`s all fine
2) But after reloading the page, it changes to:
I have no idea, why it changes, for sure it`s not browser related.
Have disabled nearly everything (Episerver plugins, rewrites, adding custom headers) - and still it`s the same.
All I can think of is that is some crazy Episerver issue (v9.12), but it gets even worse, as it behaves the same when I change the ContentOutputCache to OutputCache.
I'm experiencing the same problem with max-age, but only on Azure, not on my local IIS.
Did you find a solution Michael?
Can you clarify these items:
Turns out it has nothing to do with Episerver. It's a regression in .NET 4.6.2, see https://github.com/Microsoft/dotnet/issues/330
Kristian You just saved my day, as I was going to investigate it today. Kudos man!
