Abstract: A page structure may be used to begin validation of an embedded resource prior to the time a browser issues a request to validate the embedded resource. A page structure includes information indicating one or more embedded resources in the web page and, in some implementations, its corresponding cache characteristics. The page structure may be used to generate a validation message that indicates resources to be validated. The validation message may be sent to a server at substantially the same time that the browser begins rendering the web page. The server can then begin validating the resources indicated in the validation message by sending validation requests to an origin or other server storing the embedded resources. The server then may send the validation responses back to the client computer executing the browser so that the validation responses can be used to satisfy corresponding validation requests generated by the browser.

Abstract: A method and system for improving data access times for a client system located remote from a central server. One example system includes the client system, the central server, and a client web cache located in close geographical proximity to the client system. The central server receives data requests from the client system and retrieves the data from the appropriate data source. The central server also sends the requested data and scripts to the local client web cache for instructing the client web cache to store the cache data. Alternatively, client web cache may have received a prior one-time instruction to cache predetermined types of data. The client web cache receives the data from the central server and based on the scripts or the one-time instruction, and caches the cache data, as instructed. The cache data may then be accessed by the client system.
