How it Works

Site Distribution is based on a reverse proxy cache paradigm. When an end user requests a piece of content, the end user is directed to an edge server that is near them � based on a complex load balancing process. Once the end user is directed to the local edge server, the cache server makes a determination if it has the item in its local repository. If it does, it delivers that content to the end user. In the event that the content item is not in cache, the edge server will retrieve that item from the origin server and serve it out to the end user. Subsequently, the item requested is now stored in cache. This allows for efficient use of the edge caches by not requesting content that is not needed by end users, sometimes referred to as limiting cache pollution.

How does Site Distribution differs from other caching solutions on the market?

Site Distribution delivers your Web content from servers close to your end users, ensuring a high-quality experience for every visitor. Unlike other content distribution offerings that provide services from a set of centralized servers, Site Distribution delivers your content from local delivery points � bypassing Internet peering limitations and transit bandwidth congestion as well as mitigating bottlenecks at the origin. As a result, end users receive a superior quality of service.

Additional Options Available:

• Log Delivery: email or FTP of your log files
• Site Failover: actively monitor your origin and deliver a static Web page in the event your origin is not available
• Secure Whole Site Delivery: SSL delivery using your hostname
