HybridCache: Enable setting expiration based on value in factory

[lindeberg]

Is there an existing issue for this?

• I have searched the existing issues

Is your feature request related to a problem? Please describe the problem.

My HybridCache factory is fetching data from an HTTP API. The fetch response includes a maxAge header, from which I want to set cache expiration.

There's no way of getting the value from the factory method to the expiration setting.

Describe the solution you'd like

Some way to enable this

Additional context

No response

we also need such feature. maybe change "HybridCacheEntryOptions? options" in method signature to "Func<T, HybridCacheEntryOptions?>" ?

This should not be "hard" to do but brings a lot of value since one can set expiration depending on the factory response.

Hi, folks.
I am just highlighting that it was also requested in the discussions/forum here: #57021

The demand is noted. We can try to look at what we can add here.

Without this feature we have to continue with our MemoryCache and IDistirbutedCache combination

@palcarlsen if you have this specific need, you can meanwhile use FusionCache, which supports this in the form of adaptive caching.

You can use it now directly and in the future, if you want, switch to use the HybridCache adapter and then, again if desired, change the implementation to the Microsoft one when this feature may become available.

Hope this helps.
