How to efficiently cache dynamic content in asp.net mvc?

"Blogging on App Engine, part 1: Static serving" describes how to properly handle dynamic content caching when using python with GAE. It covers DownStream caching, conditional GETs, 404 responses, Etags... I haven't found a开发者_开发百科nything as comprehensive related to a targeted asp.net mvc implementation.

What would be the most elegant/readable/maintainable way to implement this when targeting asp.net mvc platform ?

EDIT: "Enabling Client-Side Caching of Generated Content in ASP.NET" provides one with some interesting insight about the subject.

Combining the OutputCache attribute (which Yannis suggests) and modifying the HttpContext should work.

There's some information about conditional GETs and Etags: Conditional GETs and Etags

If someone knows a better way to solve this problem: I'm interested :-)
