Site acceleration with customer prefetching enabled through customer-specific configurations

摘要

A CDN edge server is configured to provide one or more extended content delivery features on a domain-specific, customer-specific basis, preferably using configuration files that are distributed to the edge servers using a configuration system. A given configuration file includes a set of content handling rules and directives that facilitate one or more advanced content handling features, such as content prefetching. When prefetching is enabled, the edge server retrieves objects embedded in pages (normally HTML content) at the same time it serves the page to the browser rather than waiting for the browser's request for these objects. This can significantly decrease the overall rendering time of the page and improve the user experience of a Web site.

1. A computer program product in a non-transitory computer readable medium adapted to be executed in a data processing system having a hardware element, comprising:
program code to receive configuration data, the configuration data associated with a content provider domain of one of a set of content providers; program code operative as a given object associated with the content provider domain is being served to a requesting client, to scan a response body of the given object to identify one or more content objects identified in the response body that may be candidates for prefetching; program code operative for at least one content object identified in the response body that may be a candidate for prefetching, to create a request for the content object; and program code operative as the given object associated with the content provider domain is being served, to execute the request to attempt to fetch the content object if when a prefetching status for the content provider domain has been enabled and a given prefetch limit has not been exceeded, the prefetching status and the given prefetch limit being identified by the configuration data.
