Content is dynamically assembled at the edge of the Internet, preferably on content delivery network (CDN) edge servers. A content provider leverages an 'edge side include' (ESI) markup language that is used to define Web page fragments for dynamic assembly at the edge. Dynamic assembly improves site performance by caching objects that comprise dynamically-generated pages at the edge of the Internet, close to the end user. Instead of being assembled by an application/web server in a centralized data center, the application/web server sends a page template and content fragments to a CDN edge server where the page is assembled. Each content fragment can have its own cacheability profile to manage the 'freshness' of the content. Once a user requests a page, the edge server examines its cache for the included fragments and assembles the page on-the-fly.

Dynamic content assembly on edge-of network servers in a content delivery network

Dynamic content assembly on edge-of-network servers in a content delivery network

A 'velvet rope' mechanism that enables customers of a shared distributed network (such as a content delivery network) needing to control their costs to control the amount of traffic that is served via the shared network. A given server in the distributed network identifies when a customer is about to exceed a bandwidth quota as a rate (bursting) or for a given billing period (e.g., total megabytes (MB) served for a given period) and provides a means for taking a given action based on this information. Typically, the action taken would result in a reduction in traffic served so that the customer can constrain its usage of the shared network to a given budget value.

Method and system for constraining server usage in a distributed network

The disclosed technique enables a content provider to dynamically assemble content at the edge of the Internet, preferably on content delivery network (CDN) edge servers. Preferably, the content provider leverages an 'edge side include' (ESI) markup language that is used to define Web page fragments for dynamic assembly at the edge. Dynamic assembly improves site performance by catching the objects that comprise dynamically generated pages at the edge of the Internet, close to the end user. The content provider designs and develops the business logic to form and assemble the pages, for example, by using the ESI language within its development environment. Instead of being assembled by an application/web server in a centralized data center, the application/web server sends a page template and content fragments to a CDN edge server where the page is assembled. Each content fragment can have its own cacheability profile to manage the 'freshness' of the content. Once a user requests a page (template), the edge server examines its cache for the included fragments and assembles the page on-the-fly.
