Question

Can someone point out a couple of good quality tutorials/pages for donut caching? Like everything else on the web, you can google a million things, but several of the articles I've found are a bit confusing.

I'm looking for

1. What is donut caching
2. When should you use it
3. How do you implement in ASP.net

Answer 1

Donut caching is where you cache every thing on a page except a few dynamic regions. So you cache the doughnut but not the hole.

You should use it when most of you page is static other than 1 changable section.

You should read this on implementation advice.

Answer 2

1. article by Phil Haack (asp.net mvc)
2. article by ScottGu on asp.net weblogs
3. implementing donut caching on wackylabs

and all this with one google search
