Add ability to explicitly include/exclude specific actions from CacheCow support

[Crozin]

Hello. Are there any plans to add support for attribute/pattern-based option to explicitly include/exclude specific WebAPI actions in CacheCow Handler? It alread has _ignoreRequestRules but there is no way to extend/replace that filed.

Why do I ask for such an option? Sometimes only 1 or 2 actions could benefit HTTP Cache and there is no need to flood Redis or other storage with useless entries.

Thank you for your comment. Surely this can be opened up. I will do that and make a release quickly just to expose it.

Fixed and version 1.3 released to Nuget

Hey, I see Client-side of CacheCow has been upgraded, however what I was asking about was Server-side part. :-)

Any chace to reopen that Issue as it targets CacheCow.Server not CacheCow.Client? :)

[aliostad]

Sorry sure. Let me look at it.

Hi @aliostad,

Does it make sense to add the same functionality to the server-side cachinghandler?

For example:

OK, CacheCow is moving away from all that IRoutePatternProvider, and EntityTagStore. 2.0.0 is being released in a few days.
