Partial Output Caching in ASP.NET MVC

Unfortunately, the [OutputCache] filter that ships with ASP.NET MVC is merely a thin wrapper around ASP.NET output caching. The MVC team have explained that they’re aware of the issues, but it’s very difficult to make ASP.NET output caching fit into MVC’s design, and they are focusing on other things first. We can quite easily create a new caching filter that captures actions’ output and uses ASP.NET’s data caching facility to store it for next time. This filter will fit properly into the MVC pipeline, not strangely bypassing authorization or other earlier filters (it will run at the right time in whatever ordered set of filters you’ve using).
