Cache Files the Right Way: Faster Sites & Better Server Availability

Dramatically reduce page load time & increase visitor retention

Caching saves bandwidth and server resources because it reduces network traffic. This is why shared (proxy) caches exist on the Internet and corporate intranets.

Infrastructure providers and corporate IT departments make extensive investments in caching technology because the savings are too great to pass up.

Save time deploying & delegating cache control

Given normal Web browsing conditions, a cached object will always load faster than an uncached one. Our testing shows that an uncached image can take 0.5 seconds to be verified by an origin server - multiply this lag by the number of images on a page, and your users could be waiting a very long time indeed.

Cache Features

Eliminate unnecessary requests & bandwidth consumption

Caching reduces network latency by serving content from a cache located much closer to the user than the server housing the original website. This eliminates excessive conditional GET requests and 304 responses for improved site performance.

Single Text File Management

CacheRight manages all cache control rules for a site together in a single text file, promoting caching of binary objects like images, PDFs, and multimedia files.

No MMC Access Requirement

CacheRight requires no MMC access to apply cache control to IIS Web sites and applications.

Cache Control Headers

CacheRight supports all relevant HTTP 1.0 and 1.1 cache control headers including Expires and Cache-control (max-age, public/private, and no-transform).

Easy Rule Statements

CacheRight uses intuitive, easy-to-master rule statements (a sample rules file is provided with detailed examples for developers).

Global Caching Rules

CacheRight supports site-wide, directory, or file-based caching rules.
