HTML delivery from edge-of-network servers in a content delivery network
(CDN)

Abstract
A content delivery network is enhanced to provide for delivery of cacheable
markup language content files such as HTML. To support HTML delivery, the
content provider provides the CDNSP with an association of the content
provider's domain name (e.g., www.customer.com) to an origin server domain
name (e.g., html.customer.com) at which one or more default HTML files are
published and hosted. The CDNSP provides its customer with a CDNSP-specific
domain name. The content provider, or an entity on its behalf, then
implements DNS entry aliasing (e.g., a CNAME of the host to the
CDNSP-specific domain) so that domain name requests for the host cue the CDN
DNS request routing mechanism. This mechanism then identifies a best content
server to respond to a request directed to the customer's domain. The CDN
content server returns a default HTML file if such file is cached;
otherwise, the CDN content server directs a request for the file to the
origin server to retrieve the file, after which the file is cached on the
CDN content server for subsequent use in servicing other requests. The
content provider is also provided with log files of CDNSP-delivered HTML.
