Question

I have a heavy page that is cached. This is okay for anonymous users. They all see the same page.

The problem is for logged in users. They should have minor parts of the page re-rendered on every request (like personal notes on content in the page, etc.)
But still all the rest of the page should be cached (it does tons of SQL and calcuations when rendered).

As a workaround I put placeholders in page templates (like #var1#, #var2#,..).
Then I make controller method to render View into string, where I do string.Replace #var1# and other into real values.

Any cleaner way to do such kind of partial “non-caching”?

Answer 1

This is called donut caching.

The ASP.Net MVC framework doesn’t currently support it, but it’s planned for version 3.
