US Patent 8626876 Intermediate content processing for content delivery networks

An intermediate server for handling content requests received from edge servers in a Content Delivery Network (CDN) and accessing and processing content distributed throughout the CDN may include a port that receives a content request from an edge server in a same Point-of-Presence (POP) including a URI. The ICPS may also include a content processor communicatively coupled to the port and configured to perform a processing function on the requested content to produce processed content for delivery to the edge server. The ICPS may further include a CDN content interface that provides virtualized access to content files accessible using URIs throughout the CDN and configured to receive a portion of the requested content using the URI stored in a second POP, and provide the requested content to the content processor, wherein the requested content comprises the portion of the requested content.
