Cache Files the Right Way for Faster Sites and Better Server Availability

Providing Powerful Cache Control Management for IIS servers

• Dramatically reduce page load time, resulting in a better user experience and increased visitor retention
• Eliminate unnecessary requests and bandwidth consumption due to excessive conditional GET requests and 304 responses
• Save time deploying cache control by centralizing rules in one file
• Delegate cache control to developers, freeing up admins for other tasks

Caching indisputably 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.

Improved site performance is simply the other side of this coin; caching reduces network latency. It does this by serving content from a cache located much closer to them than the Web server housing the original web site.

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.
