CacheRight adds the ability to set reliable caching policies for any site content in the hands of site developers. Developers who want full control over how caching happens no longer need access to IIS's administrative interface. A simple configuration file in the website's home directory lets them set up rules that control expiration times by file location or type. Unchanging images like navigation bars, company logos, and product shots can at last be cached correctly - improving the user's experience while dramatically reducing both bandwidth consumption and server load.
