HTML delivery from edge-of-network servers in a content delivery network (CDN)
First Claim
1. A method operative in a content delivery network (CDN) wherein participating content providers identify content to be served from a set of CDN content servers in response to DNS queries that are resolved through a domain name service managed by a CDN service provider (CDNSP), wherein the domain name service is authoritative only for given content domains associated with the participating content providers, comprising:
- responsive to an end-user request for a web page that is directed to a participating content provider domain, using a CDNSP-specific domain to cue the domain name service, wherein the domain name service then resolves the CDNSP-specific domain to identify a CDN content server;
determining whether a default markup language file associated with the web page exists on the CDN content server identified by the domain name service; and
if the default markup language file exists on the CDN content server identified by the domain name service, serving the default markup language file in response to the end-user request for the web page, and logging data associated with the default markup language file served;
if the default markup language file does not exist on the CDN content server identified by the domain name service, directing a request for the default markup language file to a second server, receiving the default markup language file at the CDN content server, serving the default markup language file in response to the end-user request for the web page, and logging data associated with the default markup language file served.

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.
