The IIS 7.0 output cache is a new feature that makes it possible to cache entire responses in memory, even from dynamic content. Unlike existing caches in IIS 6.0, IIS 7.0 has a “smart” cache, which lets site owners and developers configure the output cache to cache separate copies of responses based on query string value. The output cache is also integrated with the HTTP.sys kernel cache that helps with fast performance. Kernel caching is unlocked by default. Developers can take advantage of this feature by configuring caching profiles within their application. You can run a command line tool that shows what content is in the HTTP.sys cache.
To view the HTTP response cache
- Open a command prompt and run the following:
netsh http show cache
