CacheRight is an ISAPI add-onfor IIS, that puts the ability to set reliable caching policies for anysite content in the hands of site developers, without access to IISs administrative interface. It uses a simple configuration file in the website s home directory, that lets them set up rules that control expiration times (and other import cache control information) by file location or type. With CacheRight, unchanging images like navigation bars, company logos and product shots can be cached correctly improving the user s experience while reducing both bandwidth consumption and server load. CacheRight also promotes caching of binary objects such as images and supports site-wide, directory or file-based caching rules as well as rules based on MIME type of requested object.S supports all relevant HTTP 1.0 and 1.1 cache control headers including Expires, Cache-control: max-age, public/private and no-transform. CaheRight offers all the feature that are offered by IIS (without need to access the MMC) and also offers some additional features like global content expiration based on MIME type.
