[ResponseCache] for Blazor static server rendering

[danroth27]

In MVC & Razor Pages we have attributes, like ResponseCacheAttribute and OutputCacheAttribute, for configuring response & output caching on a page or action. We should consider having similar support for Blazor server-side rendering.

We've moved this issue to the Backlog milestone. This means that it is not going to be worked on for the coming release. We will reassess the backlog following the current release and consider this item at that time. To learn more about our issue management process and to have better expectation regarding different types of issues you can read our Triage Process.

This useful especially in the context of using server-side rendering (SSR) to gain performance.

Adding support for caching components would server those who are building apps relying on parts if a web page being cached due to high-load. E-commerce sites and sites selling tickets to concerts etc.

Also worth mentioning:

In MVC Razor and Razor Pages, you can cache certain portions of a view using a tag helper. So apart from attributes you can have a special Cache component as well.

<Cache ExpiresAfter="@TimeSpan.FromSeconds(120)">
    @DateTime.Now
</Cache>
