Dynamic selection of resources for compression in a content delivery network

摘要

Embodiments provide a compression proxy service that dynamically selects resources or other content for compression and delivery to user devices. The resources are selected based on evaluation of compression characteristics relating to the resources. A manifest is defined to identify the selected resources, or to identify the resources not selected for processing by the compression proxy service. The user devices employ the manifest to determine whether to send requests for the resources to the compression proxy service or to another source (e.g., an origin web site). Some embodiments provide a reduction in network traffic while making efficient use of the compression proxy service.

主权项

1. A method comprising:
receiving, by a compression proxy service, a request for a plurality of resources; compressing the requested plurality of resources; generating compression characteristics based on the compressing of the requested plurality of resources; evaluating the generated compression characteristics of the requested plurality of resources; selecting one or more of the resources based on the evaluated compression characteristics; and defining a manifest, indicating the selected one or more of the resources therein, for use by a computing device to subsequently identify which of the plurality of resources to obtain from the compression proxy service, wherein defining the manifest comprises updating a previously defined manifest.
