FlashEdge CDN (Content Delivery Network) is a web service that speeds up the delivery of your static and dynamic web content, such as .html, .css, .js, and image files, to your users. FlashEdge delivers your content through a worldwide network of data centers called edge locations. When a user requests content that you're serving with FlashEdge, the request is routed to the edge location that provides the lowest latency (time delay), so that content (typically images or other static files) is delivered with the best possible performance.
