ASP.NET 2.0 introduces a new feature called Post-Cache Substitution, which is aimed at optimizing the development experience for this mostly-cached page scenario. Rather than requiring page developers to mark page regions (user controls) as cached, post-cache substitution allows them to output cache an entire page and then simply identify regions of the page that should be exempt from caching. It also allows control developers to prevent their rendering from from being cached. In the above example, an AdRotator control that takes advantage of post-cache substitution would be able to serve a different advertisement on each request even if its parent page were cached.

About the Author

The ASP.NET Wiki was started by Scott Hanselman in February of 2008. The idea is that folks spend a lot of time trolling the blogs, googlinglive-searching for answers to common "How To" questions. There's piles of fantastic community-created and MSFT-created content out there, but if it's not found by a search engine and the right combination of keywords, it's often lost.

The ASP.NET Wiki articles moved to CodeProject in October 2013 and will live on, loved, protected and updated by the community.
